Get ad accounts accessible by a user.

amount_spent and balance are returned in currency units (e.g. USD dollars),
not cents.

Args:
    access_token: Meta API access token (optional - will use cached token if not provided)
    user_id: Meta user ID or "me" for the current user
    limit: Maximum number of accounts to return (default: 200)

Get detailed information about a specific ad account.

Args:
    account_id: Meta Ads account ID (format: act_XXXXXXXXX)
    access_token: Meta API access token (optional - will use cached token if not provided)
    fields: Optional comma-separated Graph API fields to return. When provided,
            replaces the default field set. Useful for fetching extras like
            funding_source_details, spend_cap, is_prepay_account, min_daily_budget,
            disable_reason, capabilities. Default fields:
            id, name, account_id, account_status, amount_spent, balance, currency,
            age, business_city, business_country_code, timezone_name.
            For prepaid accounts (is_prepay_account=true, common in Brazil), the
            Business Manager "available balance" is the sum of funding_source_details
            STORED_BALANCE entries plus coupons — the `balance` field alone is the
            amount due to be billed, not the available pre-paid funds.

Get campaigns for a Meta Ads account with optional filtering.

Note: By default, the Meta API returns a subset of available fields. 
Other fields like 'effective_status', 'spend_cap', 'budget_remaining',
'promoted_object', 'source_campaign_id', etc., might be available but
require specifying them in the API call (currently not exposed by this
tool's parameters).

Args:
    account_id: Meta Ads account ID (format: act_XXXXXXXXX)
    access_token: Meta API access token (optional - will use cached token if not provided)
    limit: Maximum number of campaigns to return (default: 10)
    status_filter: Filter by effective status (e.g., 'ACTIVE', 'PAUSED', 'ARCHIVED').
                   Maps to the 'effective_status' API parameter, which expects an array
                   (this function handles the required JSON formatting). Leave empty for all statuses.
    objective_filter: Filter by campaign objective(s). Can be a single objective string or a list of objectives.
                     Valid objectives: 'OUTCOME_AWARENESS', 'OUTCOME_TRAFFIC', 'OUTCOME_ENGAGEMENT',
                     'OUTCOME_LEADS', 'OUTCOME_SALES', 'OUTCOME_APP_PROMOTION'.
                     Examples: 'OUTCOME_LEADS' or ['OUTCOME_LEADS', 'OUTCOME_SALES'].
                     Leave empty for all objectives.
    after: Pagination cursor to get the next set of results

Get detailed information about a specific campaign.

Note: This function requests a specific set of fields ('id,name,objective,status,...'). 
The Meta API offers many other fields for campaigns (e.g., 'effective_status', 'source_campaign_id', etc.) 
that could be added to the 'fields' parameter in the code if needed.

Args:
    campaign_id: Meta Ads campaign ID
    access_token: Meta API access token (optional - will use cached token if not provided)

Create a new Facebook or Instagram ad campaign in a Meta Ads account. Use this to start
a new campaign with an ODAX objective (OUTCOME_LEADS, OUTCOME_SALES, OUTCOME_AWARENESS,
OUTCOME_TRAFFIC, OUTCOME_ENGAGEMENT, OUTCOME_APP_PROMOTION), pick CBO (campaign budget
optimization) or ABO (ad-set-level budgets), and set bid strategy, spend cap, and special
ad categories. This is the first step of the campaign group → ad set → ad hierarchy on
Meta. Returns the new campaign id. Also known as: create campaign, new campaign, make
campaign, campaign group, ABO campaign, CBO campaign.

Note: Campaigns do not support start_time for scheduling — set start_time on the ad set instead.

Args:
    account_id: Meta Ads account ID (format: act_XXXXXXXXX)
    name: Campaign name
    objective: Campaign objective (ODAX, outcome-based). Must be one of:
               OUTCOME_AWARENESS, OUTCOME_TRAFFIC, OUTCOME_ENGAGEMENT,
               OUTCOME_LEADS, OUTCOME_SALES, OUTCOME_APP_PROMOTION.
               Note: Legacy objectives like BRAND_AWARENESS, LINK_CLICKS,
               CONVERSIONS, APP_INSTALLS, etc. are not valid for new
               campaigns and will cause a 400 error. Use the outcome-based
               values above (e.g., BRAND_AWARENESS → OUTCOME_AWARENESS).
    access_token: Meta API access token (optional - will use cached token if not provided)
    status: Initial campaign status (default: PAUSED)
    special_ad_categories: List of special ad categories if applicable
    daily_budget: Daily budget in account currency (in cents) as a string (only used if use_adset_level_budgets=False)
    lifetime_budget: Lifetime budget in account currency (in cents) as a string (only used if use_adset_level_budgets=False)
    buying_type: Buying type (e.g., 'AUCTION')
    bid_strategy: Bid strategy (default: LOWEST_COST_WITHOUT_CAP). Must be one of: 'LOWEST_COST_WITHOUT_CAP', 'LOWEST_COST_WITH_BID_CAP', 'COST_CAP', 'LOWEST_COST_WITH_MIN_ROAS'. WARNING: If you use LOWEST_COST_WITH_BID_CAP or COST_CAP, all child ad sets will require bid_amount to be set.
    bid_cap: Bid cap in account currency (in cents) as a string
    spend_cap: Spending limit for the campaign in account currency (in cents) as a string
    campaign_budget_optimization: Whether to enable campaign budget optimization (only used if use_adset_level_budgets=False)
    ab_test_control_setups: Settings for A/B testing (e.g., [{"name":"Creative A", "ad_format":"SINGLE_IMAGE"}])
    use_adset_level_budgets: If True, budgets will be set at the ad set level instead of campaign level (default: False)

Update an existing campaign in a Meta Ads account.

Note: Campaigns do not support start_time for scheduling — set start_time on the ad set instead.

Migrating CBO (Advantage Campaign Budget) → ABO (ad set level budgets):
    Pass `adset_budgets` with one entry per ad set in the campaign. Meta atomically
    removes the campaign-level budget and assigns budgets at the ad set level in a
    single call. This is Meta's documented mechanism — the legacy
    `use_adset_level_budgets=true` flag attempts to clear `daily_budget`/`lifetime_budget`
    but Meta silently ignores the empty values, so the migration does not persist.

Args:
    campaign_id: Meta Ads campaign ID
    access_token: Meta API access token (optional - will use cached token if not provided)
    name: New campaign name
    status: New campaign status (e.g., 'ACTIVE', 'PAUSED')
    special_ad_categories: List of special ad categories if applicable
    daily_budget: New daily budget in account currency (in cents).
    lifetime_budget: New lifetime budget in account currency (in cents).
    bid_strategy: New bid strategy
    bid_cap: New bid cap in account currency (in cents) as a string
    spend_cap: New spending limit for the campaign in account currency (in cents) as a string
    campaign_budget_optimization: Enable/disable campaign budget optimization
    objective: New campaign objective (Note: May not always be updatable)
    use_adset_level_budgets: Deprecated for CBO → ABO migration — use `adset_budgets`
        instead. Kept for backwards compatibility; sends empty `daily_budget`/
        `lifetime_budget` which Meta silently ignores in most cases.
    adset_budgets: List of `{"adset_id": "...", "daily_budget": <cents>}` objects.
        Use to migrate from CBO to ABO: Meta removes the campaign-level Advantage
        budget and assigns the provided daily budgets at the ad set level in one
        atomic call. Example:
            [{"adset_id": "1234", "daily_budget": 5000},
             {"adset_id": "5678", "daily_budget": 7000}]

    campaign_id: Meta Ads campaign ID this ad set belongs to
    name: Ad set name
    optimization_goal: Conversion optimization goal. Valid values depend on the campaign objective and destination_type.
                      OUTCOME_ENGAGEMENT + destination_type=WEBSITE: OFFSITE_CONVERSIONS, LANDING_PAGE_VIEWS, LINK_CLICKS, IMPRESSIONS, REACH.
                      OUTCOME_ENGAGEMENT + On Post: POST_ENGAGEMENT, IMPRESSIONS, REACH.
                      OUTCOME_ENGAGEMENT + On Video: THRUPLAY, TWO_SECOND_CONTINUOUS_VIDEO_VIEWS.

                      OUTCOME_TRAFFIC + WEBSITE: LANDING_PAGE_VIEWS, LINK_CLICKS, IMPRESSIONS, REACH.
                      OUTCOME_AWARENESS: REACH, IMPRESSIONS, AD_RECALL_LIFT, THRUPLAY.

                      OUTCOME_SALES: OFFSITE_CONVERSIONS, VALUE, CONVERSATIONS, LINK_CLICKS, IMPRESSIONS, REACH.
                      OUTCOME_APP_PROMOTION: APP_INSTALLS, APP_INSTALLS_AND_OFFSITE_CONVERSIONS, VALUE.
    billing_event: How you're charged (e.g., 'IMPRESSIONS', 'LINK_CLICKS')
    status: Initial ad set status (default: PAUSED)
    daily_budget: Daily budget in account currency (in cents) as a string.
                 CBO NOTE: Do NOT set this if the parent campaign already has a budget
                 (Campaign Budget Optimization / CBO mode). Meta only allows budgets at one
                 level: either the campaign OR the ad set, not both. If the campaign has a
                 daily_budget or lifetime_budget, omit this field — the ad set will
                 automatically use the campaign budget.
    lifetime_budget: Lifetime budget in account currency (in cents) as a string.
                    CBO NOTE: Do NOT set this if the parent campaign already has a budget
                    (Campaign Budget Optimization / CBO mode). Omit this field when the
                    campaign uses CBO — the ad set inherits the campaign budget automatically.
    targeting: Targeting specs (age, location, interests, etc).
              targeting_automation.advantage_audience defaults to 0 if not set (Meta API v24+ requirement).
              Set to 1 to enable Advantage+ Audience (requires age_max>=65). Use search_interests for interest IDs.
    bid_amount: Bid amount in account currency (in cents).
               REQUIRED for: LOWEST_COST_WITH_BID_CAP, COST_CAP, TARGET_COST.
               NOT USED by: LOWEST_COST_WITH_MIN_ROAS (uses bid_constraints instead).
               May also be required if the parent campaign's bid strategy requires it.
    bid_strategy: Bid strategy. Valid values:
                 - 'LOWEST_COST_WITHOUT_CAP' (recommended) - no bid_amount required
                 - 'LOWEST_COST_WITH_BID_CAP' - REQUIRES bid_amount
                 - 'COST_CAP' - REQUIRES bid_amount
                 - 'LOWEST_COST_WITH_MIN_ROAS' - REQUIRES bid_constraints with roas_average_floor,
                   and optimization_goal='VALUE'. Does NOT use bid_amount.
                 Note: 'LOWEST_COST' is NOT valid - use 'LOWEST_COST_WITHOUT_CAP'.
                 Campaign-level bid strategy may constrain ad set choices.
    bid_constraints: Bid constraints dict. Required for LOWEST_COST_WITH_MIN_ROAS.
                    Use {"roas_average_floor": <value>} where value = target ROAS * 10000.
                    Example: 2.0x ROAS -> {"roas_average_floor": 20000}
    bid_adjustments: Bid multipliers per targeting dimension. Pass-through to Meta.
                    Shape: {"user_groups": {"<dim>": {"<value>": <float>, "default": <float>}}}
                    Dims: age, gender, user_os, device_platform, position_type,
                          publisher_platform, user_bucket, home_location, locale, etc.
                    Multipliers are floats, typically 0.0-1.0.
                    Example: {"user_groups": {"user_os": {"iOS": 0.9, "Android": 0.7, "default": 1.0}}}
                    NOTE: Writing bid_adjustments requires a Meta app capability that must be
                          allowlisted. Apps without it get OAuthException (#3).
    start_time: Start time in ISO 8601 format (e.g., '2023-12-01T12:00:00-0800').
               To schedule future delivery: set start_time to a future date and status=ACTIVE.
               Meta will show effective_status as SCHEDULED and automatically begin delivery at start_time.
               NOTE: Only ad set start_time controls delivery scheduling. Campaigns do not support start_time.
    end_time: End time in ISO 8601 format. Required when lifetime_budget is specified.
    dsa_beneficiary: DSA beneficiary for European compliance (person/org that benefits from ads).
                    Required for EU-targeted ad sets along with dsa_payor.
    dsa_payor: DSA payor for European compliance (person/org paying for the ads).
               Required for EU-targeted ad sets along with dsa_beneficiary.
    promoted_object: App config for APP_INSTALLS. Required: application_id, object_store_url.
    destination_type: Where users go after click. Common values: 'WEBSITE', 'WHATSAPP', 'MESSENGER',
                     'INSTAGRAM_DIRECT', 'ON_AD', 'APP', 'FACEBOOK', 'SHOP_AUTOMATIC'.
                     Also supports multi-channel combos like 'MESSAGING_MESSENGER_WHATSAPP'.
    is_dynamic_creative: Enable Dynamic Creative for this ad set.
    frequency_control_specs: Frequency cap specs. MUST be set at creation time — Meta makes this field
                             immutable after the ad set is created (error 1815198).
                             Only works with OUTCOME_AWARENESS campaigns + optimization_goal REACH or THRUPLAY.
                             Example: [{"event": "IMPRESSIONS", "interval_days": 7, "max_frequency": 1}]
    multi_advertiser_ads: Set to 0 to opt out of Multi-Advertiser Ads, 1 to opt in.

                                   INDIA_FINSERV, SINGAPORE_UNIVERSAL, THAILAND_UNIVERSAL.
                                   Example: ["TAIWAN_UNIVERSAL"] or ["TAIWAN_FINSERV", "TAIWAN_UNIVERSAL"]
    regional_regulation_identities: Dict of verified identity IDs for regional transparency compliance.
                                    Required when regional_regulated_categories is set.
                                    The identity IDs come from completing advertiser verification in Meta Business Settings.
                                    Keys depend on the categories declared:
                                    - TAIWAN_UNIVERSAL: taiwan_universal_beneficiary, taiwan_universal_payer

                                    Example: {"taiwan_universal_beneficiary": "<id>", "taiwan_universal_payer": "<id>"}
    attribution_spec: Attribution window specification for the ad set. Controls how conversions are
                     attributed to ads. Default is 7-day click if not specified.
                     Example for 1-day click: [{"event_type": "CLICK_THROUGH", "window_days": 1}]
                     Example for 1-day click + 1-day view: [{"event_type": "CLICK_THROUGH", "window_days": 1}, {"event_type": "VIEW_THROUGH", "window_days": 1}]
                     Valid event_type values: CLICK_THROUGH, VIEW_THROUGH.

    bid_amount: Bid amount in cents. Required for LOWEST_COST_WITH_BID_CAP, COST_CAP, TARGET_COST.
               NOT USED by LOWEST_COST_WITH_MIN_ROAS (uses bid_constraints instead).

    access_token: Meta API access token (optional - will use cached token if not provided)
    limit: Maximum number of ads to return (default: 10)
    campaign_id: Optional campaign ID to filter by
    adset_id: Optional ad set ID to filter by

Get detailed information about a specific ad.

Args:
    ad_id: Meta Ads ad ID
    access_token: Meta API access token (optional - will use cached token if not provided)

Args:
    creative_id: Meta Ads creative ID (required)
    access_token: Meta API access token (optional)

Create a new ad with an existing creative.

Args:
    account_id: Meta Ads account ID (format: act_XXXXXXXXX)
    name: Ad name
    adset_id: Ad set ID where this ad will be placed
    creative_id: ID of an existing creative to use

                  Example: [{"action.type":"offsite_conversion","fb_pixel":["YOUR_PIXEL_ID"]}]
    access_token: Meta API access token (optional - will use cached token if not provided)

Note:
    Dynamic Creative creatives require the parent ad set to have `is_dynamic_creative=true`.
    Otherwise, ad creation will fail with error_subcode 1885998.

Get creative details for a specific ad. Requires an ad_id (not account_id). Use get_ads first to find ad IDs.

Args:
    ad_id: Meta Ads ad ID (required)
    access_token: Meta API access token (optional - will use cached token if not provided)

Get, download, and visualize a Meta ad image in one step. Useful to see the image in the LLM.

Args:
    ad_id: Meta Ads ad ID
    access_token: Meta API access token (optional - will use cached token if not provided)

Returns:
    The ad image ready for direct visual analysis

Get video details and source URL for a Meta ad video creative. Returns the video source URL
(direct download link), thumbnail URL, and metadata (title, description, duration).

Provide either ad_id (to auto-extract the video from the ad creative) or video_id directly.
Providing account_id is strongly recommended — it enables the advideos edge which works
with Business Manager tokens (avoids error 100/33 and error #10 on account-uploaded videos).

Args:
    ad_id: Meta Ads ad ID (will extract video_id from the ad creative)
    video_id: Meta video ID (use this if you already have it from get_ad_creatives)
    account_id: Ad account ID (e.g. "act_123" or "123"). Enables advideos edge lookup.
    access_token: Meta API access token (optional - will use cached token if not provided)

Update an ad with new settings.

Args:
    ad_id: Meta Ads ad ID
    name: New ad name
    status: Update ad status (ACTIVE, PAUSED, etc.)
    bid_amount: Bid amount in account currency (in cents for USD)
    tracking_specs: Optional tracking specifications (e.g., for pixel events).
    creative_id: ID of the creative to associate with this ad (changes the ad's image/content)
    access_token: Meta API access token (optional - will use cached token if not provided)

Upload an image to use in Meta Ads creatives.

Args:
    account_id: Meta Ads account ID (format: act_XXXXXXXXX)
    access_token: Meta API access token (optional - will use cached token if not provided)
    file: Data URL or raw base64 string of the image (e.g., "data:image/png;base64,iVBORw0KG...")
    image_url: Direct URL to an image to fetch and upload
    name: Optional name for the image (default: filename)

Returns:
    JSON response with image details including hash for creative creation

Compute image_crops coordinates for a source image of the given dimensions.

Returns the image_crops dict ready to pass directly to create_ad_creative
or bulk_create_ad_creatives. For each crop key the result is the largest
centered region that fits within the source image while matching the key's
aspect ratio — equivalent to "Original" crop (no content is cut off beyond
what the ratio requires).

Args:
    image_width: Width of the source image in pixels (e.g. 1080).
    image_height: Height of the source image in pixels (e.g. 1080).
    crop_keys: Optional list of specific crop keys to compute. Defaults to
        all 6 keys accepted by Meta's API:
          "100x100"  — 1:1 square (Feed, Marketplace, Search)
          "100x72"   — ~1.39:1 horizontal (Marketplace, some placements)
          "400x500"  — 4:5 portrait (Feed on mobile, Stories fallback)
          "400x150"  — ~2.67:1 wide banner (Audience Network)
          "600x360"  — ~1.67:1 horizontal (Right column, some placements)
          "90x160"   — 9:16 tall portrait (Stories)

Returns:
    JSON with the image_crops dict (ready for copy-paste into create_ad_creative),
    plus validation notes for any invalid keys requested.

Create a new ad creative using an uploaded image hash, video ID, or an existing post.

Supports five creative modes:
- **Existing post**: Provide object_story_id (format: {page_id}_{post_id}) to promote an existing
  organic or published post. No image_hash or video_id required. Optionally combine with
  asset_customization_rules to attach a 9:16 video for Story/Reels placements.
- **Simple image/video**: Single image_hash or video_id with object_story_spec
- **Multi-variant copy**: Use plural text params (messages[], headlines[], descriptions[]) to test
  multiple text variants with a single image/video. No optimization_type or is_dynamic_creative needed.
- **Dynamic Creative**: Multiple variants with dynamic_creative_spec (requires is_dynamic_creative on ad set)
- **FLEX/DOF (Advantage+)**: Set optimization_type="DEGREES_OF_FREEDOM" for Meta to auto-optimize
  across all asset combinations without requiring is_dynamic_creative on the ad set

Args:
    account_id: Meta Ads account ID (format: act_XXXXXXXXX)
    image_hash: Hash of a single uploaded image (cannot be used with image_hashes or video_id)
    access_token: Meta API access token (optional - will use cached token if not provided)
    name: Creative name
    page_id: Facebook Page ID (string or int; coerced to string)
    link_url: Destination URL for the ad. Required unless using lead_gen_form_id or
             reminder_data — with one exception: if asset_customization_rules is also
             set, link_url is required even for Lead ads. Meta accepts the creative
             without link_urls but rejects the ad at create_ad time with error 1885800
             ("Asset Customization Ads require a link"). The URL is never shown to the
             user when lead_gen_form_id is set (the CTA opens the form), but Meta still
             demands one be present on the creative. Pass any valid URL in that case
             (e.g. the Facebook page URL or your site root).
    message: Single ad copy/text (cannot be used with messages)
    messages: List of primary text variants for multi-variant copy testing (cannot be used with message).
              Each entry can be a plain string, OR a dict {"text": "...", "adlabels": [{"name": "..."}]}
              when used with asset_customization_rules that reference body_label.
    headline: Single headline for simple ads (cannot be used with headlines)
    headlines: List of headline variants for multi-variant copy testing (cannot be used with headline).
              Each entry can be a plain string, OR a dict {"text": "...", "adlabels": [{"name": "..."}]}
              when used with asset_customization_rules that reference title_label.
              Meta enforces the actual length limit; do not pre-truncate.
    description: Single description for simple ads (cannot be used with descriptions)
    descriptions: List of description variants for multi-variant copy testing (cannot be used with description).
              Each entry can be a plain string, OR a dict {"text": "...", "adlabels": [{"name": "..."}]}
              when used with asset_customization_rules that reference description_label.
    image_hashes: List of image hashes for FLEX creatives (up to 10, cannot be used with image_hash or video_id).
                 IMPORTANT: When optimization_type="DEGREES_OF_FREEDOM" (FLEX/Advantage+ mode),
                 only ONE image is served at delivery time regardless of how many hashes you provide.
                 The Meta API accepts multiple hashes without error and they all appear in
                 asset_feed_spec, but Meta silently collapses to a single image at serving time.
                 Use image_hashes with multiple entries only in non-DOF (regular dynamic creative)
                 mode. In DOF mode, pass a single hash.
    video_id: Meta video ID for video creatives (cannot be used with image_hash or image_hashes).
              Upload a video first via the Meta API, then use the returned video ID here.
              IMPORTANT: When also providing instagram_actor_id, both instagram_actor_id AND
              ad_formats=["SINGLE_VIDEO"] must be present — otherwise Meta returns error 1443048
              ("object_story_spec ill formed"). This is handled automatically: video creatives
              that include instagram_actor_id are routed through asset_feed_spec so that
              ad_formats=["SINGLE_VIDEO"] is always included in the API request.
    thumbnail_url: Thumbnail image URL for video creatives. Recommended when using video_id.
                  Meta will auto-generate a thumbnail if not provided.
    optimization_type: Optional. Valid values:
                      - "DEGREES_OF_FREEDOM": FLEX (Advantage+) creatives where Meta auto-optimizes
                        across all asset combinations. At least one multi-variant asset field required.
                        NOTE: Meta ignores asset_customization_rules for DOF creatives.
                        NOTE: When using DEGREES_OF_FREEDOM with image_hashes, providing multiple
                        hashes is accepted by the API without error, but Meta silently serves only
                        ONE image at delivery time. A warning is included in the response if multiple
                        hashes are detected. To serve multiple images, omit optimization_type and
                        enable is_dynamic_creative on the ad set instead.
                      - "PLACEMENT": Placement Asset Customization. Use with videos[]/images[] (with
                        labels) and asset_customization_rules (with video_label/image_label references)
                        to serve different aspect ratios per placement (e.g., 1:1 Feed + 9:16 Reels).
                      Other values are passed through to Meta as-is.
    dynamic_creative_spec: Dynamic creative optimization settings
    call_to_action_type: Call to action button type. Meta enum — free-form values
                        (e.g. 'MAKE_RESERVATION', 'RESERVE', 'BOOK_TABLE') are rejected with
                        code 100. Pick from the documented list. Common values:
                          BOOK_NOW         — restaurants, salons, clinics, appointments (use this for
                                             reservations — there is no MAKE_RESERVATION enum)
                          LEARN_MORE, SHOP_NOW, SIGN_UP, SUBSCRIBE, GET_QUOTE, CONTACT_US,
                          DOWNLOAD, WATCH_MORE, GET_OFFER, APPLY_NOW, CALL_NOW, MESSAGE_PAGE,
                          SEE_MENU, ORDER_NOW, BUY_NOW, WHATSAPP_MESSAGE, GET_DIRECTIONS,
                          BUY_TICKETS, EVENT_RSVP, BOOK_TRAVEL.
                        When using CALL_NOW, also provide phone_number.
    lead_gen_form_id: Lead generation form ID for lead generation campaigns. Required when using
                     lead generation CTAs like 'SIGN_UP', 'GET_OFFER', 'SUBSCRIBE', etc.
    instagram_actor_id: Instagram account ID for Instagram placements (must be a string
                       to avoid JavaScript integer precision loss for IDs exceeding
                       Number.MAX_SAFE_INTEGER). Sent as instagram_user_id inside
                       object_story_spec (Meta deprecated instagram_actor_id in Jan 2026).
                       IMPORTANT for video creatives: Meta requires ad_formats=["SINGLE_VIDEO"]
                       in asset_feed_spec alongside instagram_user_id in object_story_spec —
                       omitting either causes error 1443048 ("object_story_spec ill formed").
                       This is auto-handled: video_id + instagram_actor_id always routes through
                       asset_feed_spec so ad_formats=["SINGLE_VIDEO"] is included automatically.
    ad_formats: List of ad format strings for asset_feed_spec (e.g., ["AUTOMATIC_FORMAT"] for
               Flexible ads, ["SINGLE_IMAGE"] for single image, ["SINGLE_VIDEO"] for video).
               When optimization_type is "DEGREES_OF_FREEDOM" with image_hashes, defaults to
               ["AUTOMATIC_FORMAT"] (Flexible format). For video creatives, defaults to
               ["SINGLE_VIDEO"]. Otherwise defaults to ["SINGLE_IMAGE"].
    asset_customization_rules: List of placement-specific asset overrides for asset_feed_spec.
    phone_number: Phone number for CALL_NOW call-to-action ads (click-to-call).
                 Required when call_to_action_type is CALL_NOW. Use E.164 format
                 (e.g., "+18005551234"). The number is sent to Meta as
                 call_to_action.value.link = "tel:<phone_number>" (Meta v24
                 rejects a literal "phone_number" key with code 100). Common
                 use case: geo-routed call ads with different phone numbers
                 per ad set.
    creative_features_spec: Advantage+ Creative feature opt-ins/opt-outs. Controls individual
               creative enhancements like image_touchups, text_optimizations, inline_comment,
               add_text_overlay, music, 3d_animation, etc. Each feature is a dict with
               "enroll_status" set to "OPT_IN" or "OPT_OUT".
               Example: {"image_touchups": {"enroll_status": "OPT_IN"},
                        "inline_comment": {"enroll_status": "OPT_IN"}}
               Sent to Meta as degrees_of_freedom_spec.creative_features_spec.
    url_tags: URL tracking parameters appended to the destination URL (e.g.,
             "utm_source=facebook&utm_medium=cpc&utm_campaign=spring_sale").
             Sets the url_tags field on the creative.
    caption: Display URL shown in the ad (e.g., "example.com/shoes"). Sets the
            caption field in link_data. If not provided, Meta auto-generates it
            from the destination URL. Only applies to image (link_data) creatives.
    image_crops: Crop coordinates for different aspect ratios. Applied in link_data for
                image creatives.

                Use the compute_image_crops tool first to get the correct coordinates
                for your specific image dimensions — it computes centered crop boxes
                for any source size automatically.

                Valid crop keys (only these 6 are accepted by Meta's API):
                  "100x100"  — 1:1 square (Feed, Marketplace, Search)
                  "100x72"   — ~1.39:1 horizontal (Marketplace, some placements)
                  "400x500"  — 4:5 portrait (Feed on mobile, Stories fallback)
                  "400x150"  — ~2.67:1 wide banner (Audience Network)
                  "600x360"  — ~1.67:1 horizontal (Right column, some placements)
                  "90x160"   — 9:16 tall portrait (Stories)

                Format: {"100x100": [[x1,y1],[x2,y2]], "400x500": [[x1,y1],[x2,y2]]}
                Coordinates are pixel-based (top-left and bottom-right corners).
                The bounding box aspect ratio must match the key ratio as closely as possible.
                Image origin (0,0) is the upper-left corner.

                Omit to let Meta auto-crop (default for horizontal is 1.91:1 recommended).
    object_story_id: ID of an existing organic or published Facebook/Instagram post to promote
                    as an ad. Format: "{page_id}_{post_id}" (e.g., "124965744226834_3888007311337206").
                    When provided, image_hash and video_id are not required. page_id is also not
                    required (it is encoded in the story ID). Combine with asset_customization_rules
                    to attach a 9:16 video for Story/Reels placements while the organic post
                    serves as the feed creative — a common "Use Existing Post" workflow.
                    Example: object_story_id="124965744226834_3888007311337206",
                             asset_customization_rules=[{"placement_groups": ["STORY"],
                               "customization_spec": {"video_ids": ["890310874031162"]}}]
    disable_all_enhancements: When True, opts out of all Advantage+ Creative enhancements by
                    setting every known creative_features_spec key (image_touchups,
                    text_optimizations, video_auto_crop, etc.) to OPT_OUT and also
                    disabling contextual_multi_ads. Use when you want full creative
                    control without Meta's auto-modifications.
    event_id: Facebook Event ID for EVENT_RESPONSES campaigns. Required for
             event RSVP/ticket ads so the event card renders properly. Placed
             inside link_data.event_id, and also inside call_to_action.value
             when call_to_action_type is EVENT_RSVP or BUY_TICKETS. Use with
             link_url set to the Facebook event URL
             (https://www.facebook.com/events/EVENT_ID).
    asset_customization_rules: Lets you assign different images or videos to specific placement groups
               (e.g., feed vs. stories). Only valid with image_hashes or plural asset params.
               Each rule uses a user-friendly format that is automatically translated to
               Meta's API format (adlabels + customization_spec positions):
                 - placement_groups: list of placement group names
                   Valid values: FEED, STORY, MESSENGER, INSTREAM_VIDEO, SEARCH, SHOP,
                   AUDIENCE_NETWORK
                 - customization_spec: dict specifying the asset to use for those placements
                   Supported keys: image_hashes (list), video_ids (list),
                   bodies, titles, descriptions (text overrides)
               All image hashes referenced in rules must also be in image_hashes.
               Example (feed gets one image, stories gets another):
               [
                 {"placement_groups": ["FEED"],
                  "customization_spec": {"image_hashes": ["<feed_hash>"]}},
                 {"placement_groups": ["STORY"],
                  "customization_spec": {"image_hashes": ["<story_hash>"]}}
               ]
    videos: List of video objects for placement asset customization (multiple videos with
               different aspect ratios). Each entry: {"video_id": "...", "thumbnail_url": "...",
               "label": "my_label"}. The "label" field is converted to adlabels for use with
               asset_customization_rules video_label references. Cannot be used with video_id.
               Use with optimization_type="PLACEMENT" and asset_customization_rules.
    images: List of image objects for placement asset customization (multiple images with
               different aspect ratios). Each entry: {"image_hash": "...", "label": "my_label"}.
               The "label" field is converted to adlabels for use with asset_customization_rules
               image_label references. Cannot be used with image_hash or image_hashes.
               Use with optimization_type="PLACEMENT" and asset_customization_rules.
    reminder_data: Inline reminder event data for Instagram Reminder Ads
                  (REMINDERS_SET optimization goal). Placed in
                  object_story_spec.link_data.reminder_data. Use this instead of
                  upcoming_events (which requires an existing ig_upcoming_event_id).
                  Required fields:
                    - event_name (str): Display title of the reminder event
                    - start_time (int): Event start as a Unix timestamp (seconds)
                    - end_time (int): Event end as a Unix timestamp (seconds)
                  Example:
                    {"event_name": "Summer Sale", "start_time": 1745596800, "end_time": 1745611200}
                  The ad set must use optimization_goal=REMINDERS_SET and the placement
                  must be restricted to Instagram feeds/stories. link_url is still
                  recommended (the URL users visit after the reminder fires).
    facebook_branded_content: Branded content settings for Facebook partnership ads.
                  Used when a brand sponsors a creator's content on Facebook.
                  Format: {"sponsor_page_id": "<page_id>"} where sponsor_page_id is the
                  Facebook Page ID of the sponsoring brand. Passed as a top-level field
                  on the ad creative. The creator's page should be set as page_id.
    instagram_branded_content: Branded content settings for Instagram partnership ads.
                  Used when a brand sponsors a creator's content on Instagram.
                  Format: {"sponsor_id": "<instagram_user_id>"} where sponsor_id is the
                  Instagram account ID of the sponsoring brand. Passed as a top-level
                  field on the ad creative.

Returns:
    JSON response with created creative details

Update an existing ad creative's name or optimization settings.

IMPORTANT — Meta API limitation: The Meta API does NOT allow updating content
fields (message, headline, description, CTA, image, video, URL) on existing
creatives. Only the creative `name` and optimization settings (asset_feed_spec)
can be changed. To change ad content, create a new creative with the desired
content and update the ad to reference the new creative via `update_ad`.

    JSON response with pages associated with the account

Get performance insights for a campaign, ad set, ad or account.

Args:
    object_id: ID of the campaign, ad set, ad or account. You can also use the alias parameters below.
    account_id: Alias for object_id when querying account-level insights
    campaign_id: Alias for object_id when querying campaign-level insights
    adset_id: Alias for object_id when querying ad-set-level insights
    ad_id: Alias for object_id when querying ad-level insights
    access_token: Meta API access token (optional - will use cached token if not provided)
    time_range: Either a preset time range string or a dictionary with "since" and "until" dates in YYYY-MM-DD format
               Preset options: today, yesterday, this_month, last_month, this_quarter, maximum, data_maximum, 
               last_3d, last_7d, last_14d, last_28d, last_30d, last_90d, last_week_mon_sun, 
               last_week_sun_sat, last_quarter, last_year, this_week_mon_today, this_week_sun_today, this_year
               Dictionary example: {"since":"2023-01-01","until":"2023-01-31"}
    breakdown: Optional breakdown dimension. Valid values include:
               Demographic: age, gender, country, region, dma
               Platform/Device: device_platform, platform_position, publisher_platform, impression_device
               NOTE: platform_position is a Meta-restricted breakdown — Meta requires it to be paired
               with publisher_platform and is incompatible with the default action_breakdowns=[action_type].
               When you pass platform_position, this tool auto-adds publisher_platform and drops the
               action-typed fields (actions, action_values, conversions, cost_per_action_type) from the
               response. Use publisher_platform alone if you need action data alongside placement.
               Creative Assets: ad_format_asset, body_asset, call_to_action_asset, description_asset,
                              image_asset, link_url_asset, title_asset, video_asset, media_type,
                              creative_relaxation_asset_type, flexible_format_asset_type,
                              gen_ai_asset_type
               NOTE: Asset breakdowns (image_asset, video_asset, etc.) only return data for ads
               running with Dynamic Creative; for non-DCO ads, expect empty rows.
               NOTE: media_type collides with the default action_breakdowns=[action_type], so
               this tool auto-overrides action_breakdowns to [] when you pass media_type.
               Action-typed metrics (actions, action_values, conversions) are still returned
               but are no longer sliced by action_type alongside media_type.
               media_asset_url, media_creator, media_destination_url, media_format,
               media_origin_url, and media_text_content are NOT supported by Meta's Insights API
               (Meta returns "(#100) Tried accessing nonexisting field"). Use the asset breakdowns
               above instead.
               Campaign/Ad Attributes: breakdown_ad_objective, breakdown_reporting_ad_id, app_id, product_id
               Conversion Tracking: coarse_conversion_value, conversion_destination, standard_event_content_type,
                                   signal_source_bucket, is_conversion_id_modeled, fidelity_type, redownload
               Time-based: hourly_stats_aggregated_by_advertiser_time_zone, 
                          hourly_stats_aggregated_by_audience_time_zone, frequency_value
               Extensions/Landing: ad_extension_domain, ad_extension_url, landing_destination, 
                                  mdsa_landing_destination
               Attribution: sot_attribution_model_type, sot_attribution_window, sot_channel, 
                           sot_event_type, sot_source
               Mobile/SKAN: skan_campaign_id, skan_conversion_id, skan_version, postback_sequence_index
               CRM/Business: crm_advertiser_l12_territory_ids, crm_advertiser_subvertical_id,
                            crm_advertiser_vertical_id, crm_ult_advertiser_id, user_persona_id, user_persona_name
               Advanced: hsid, is_auto_advance, is_rendered_as_delayed_skip_ad, mmm, place_page_id,
                        marketing_messages_btn_name, impression_view_time_advertiser_hour_v2, comscore_market,
                        comscore_market_code
    level: Level of aggregation (ad, adset, campaign, account)
    limit: Maximum number of results to return per page (default: 25, Meta API allows much higher values)
    after: Pagination cursor to get the next set of results. Use the 'after' cursor from previous response's paging.next field.
    action_attribution_windows: Optional list of attribution windows (e.g., ["1d_click", "7d_click", "1d_view"]).
               When specified, actions include additional fields for each window. The 'value' field always shows 7d_click.
    action_breakdowns: Optional list of action_breakdowns to apply to action-typed metrics. Pass [] to disable
               the default action_type slicing (required when combining action data with breakdowns that collide
               with action_type, e.g. media_type — auto-applied for media_type when not set).
               Meta supports values like action_type, action_target_id, action_destination, etc.
    compact: When True, strips redundant action-type duplicates from the response
             (omni_*, onsite_web_*, offsite_conversion.fb_pixel_*, etc.) to reduce
             payload size by ~60%. The canonical action types (purchase, add_to_cart,
             view_content, etc.) are always preserved. Default: False.

Note on response size: This tool always returns a fixed set of fields (impressions, clicks,
spend, cpc, cpm, ctr, reach, actions, action_values, etc.) and cannot filter to a subset.
For large result sets (50+ rows), the actions/action_values arrays can make responses very
large (1–2MB+). If you only need specific metrics like spend or impressions, consider using
bulk_get_insights with compact=true and the fields parameter:
    bulk_get_insights(level="ad", account_ids=[...], compact=true, fields=["spend", "impressions"])
bulk_get_insights supports level="ad", "adset", "campaign", and "account".

Fetch a record previously returned by the 'search' tool in the same session.

IMPORTANT LIMITATIONS:
- This tool ONLY returns records that were cached by a prior 'search' call.
  It does NOT make direct API calls to Meta. If the record was not found by
  'search' first, this tool will return "Record not found".
- Do NOT use this tool to look up campaigns, adsets, or ads by ID directly.

For direct lookups by ID, use these tools instead:
- get_campaign_details(campaign_id=...) - for campaigns
- get_adset_details(adset_id=...) - for ad sets
- get_ads(account_id=..., campaign_id=...) - for ads
- get_adsets(account_id=..., campaign_id=...) - for ad sets in a campaign

Args:
    id: The record ID to fetch (format: "type:id", e.g., "account:act_123456").
        Must have been returned by a previous 'search' call.

Returns:
    JSON response with record data, or "Record not found" if the record
    was not previously cached by 'search'.
