Search webmasters (affiliates) — a webmaster is a whole ad NETWORK (landing domains, pixels, pages and geos grouped as one). Copy workflow: search by domain, take the canonical UUID, then search_creatives/search_ads with webmaster_id. Finish with the most reused material: get_webmaster.top_creatives or search_creatives sort_by=total_ads; total_ads is how many ads reuse the same material over its lifetime, not a weekly debut count. Returns total/active counts, top countries and geo counts. Find by name or pixel_id/domain/page_id/resolved_ip. Filter by category, AI category/subcategory, countries, languages, platforms, format, current status, dates and count ranges. For a geo ranking combine countries + min_geo_share + sort_by=relevance. Save returned UUIDs with add_to_favorites. Exact pixel_id/domain/page_id/resolved_ip lookups use the webmaster's CURRENT canonical identifier membership; historical identifiers removed from a webmaster do not count as matches. Exact page_id results report fanpages_status as available, partial, unavailable or not_applicable. When available, the selected page is included in fanpages[] with life_status from the same page-lifetime source as /advertisers (alive/deleted/banned, or unknown when lifetime coverage has no row); when unavailable, an omitted fanpages[] is not evidence that the page is alive. FREE PLAN COUNTS: when the plan's archive window narrows a request, pagination.total_status is "restricted" and meta.plan_window_cutoff names the boundary — the count then describes the window actually searched, NOT the one requested, so a zero means "nothing in the archive window" and never "nothing exists". QUOTA: 1 token per DELIVERED result from your plan balance (free starter: 500 tokens lifetime; paid plans: 40,000/month; short pages auto-refund — you pay only for results you receive). Default page is 20 results = 20 tokens; pass `limit` (1–200) to size it. get_usage is free. Autonomous agents must be linked to a spytrend account to access data — an unlinked agent gets an actionable connect-your-account refusal (create agent credentials at spytrend.com/settings?tab=ai, or a human claims it by client_id), NOT a server error. Calls are rate-limited per authenticated user (deployment defaults: 60/minute and 1000/hour); a rate-limit refusal is an MCP tool error with structured error.code=rate_limit_exceeded, scope, window and retry_after_seconds. CONCURRENCY: heavy analytical calls (get_trends, search_ads, search_creatives) are admitted ONE AT A TIME per account — fanning out 5-10 of them in parallel does not go faster, it returns admission refusals for all but one. Issue heavy calls sequentially; light lookups (get_ad, get_advertiser, get_usage) are not gated. TIKTOK SOURCE: pass source="tiktok" to query the TIKTOK ad corpus instead of Meta. (The platforms filter does NOT do this — platforms are Meta publisher placements.) ⚠️ TIKTOK IS PAID PER ROW at a premium: every DELIVERED TikTok ad row costs 100 tokens and every TikTok webmaster row/card costs 100 tokens (Meta rows cost 1), deducted from the same token balance (free starter: 500 tokens total = 5 TikTok rows EVER; paid plans: 40,000/month = up to 400 TikTok rows). Request small limits and narrow filters; you are charged only for rows actually delivered (short pages auto-refund; if the balance covers only part of the request, that part is delivered — a 3-row request on a 150-token balance returns 1 row and charges 100). TikTok requires a Pro-or-higher plan: free/starter callers and unlinked agents get an actionable upgrade refusal, never data and never a charge. TikTok rows have their OWN shape, returned under tiktok_data (verified live 2026-07-30): id/external_id (TikTok ad id), advertiser{id,external_id,name} plus advertiser_id (TikTok BUSINESS id), start_date/end_date (the ad's delivery window) and first_seen_date/last_seen_date (SpyTrend indexing), days_active, is_active + status_today, ai_category/ai_subcategory, countries + targeting_geos + targeting_details (OS/age/gender/regions), audience_size, objective, sponsor (the 'paid for by' funder) and registry_location, landing_domain + link_url, body/title/call_to_action, creative_format, creative_id, creative_ad_count (how many ads reuse that creative), is_blurred/is_cloaked, and media[] with media_type + thumbnail_url on media-tt.spytrend.com. Media comes WITH the row — do NOT call get_media for TikTok ids (it serves Meta entities only). There are no TikTok engagement counters (plays/likes/comments/shares) on this surface. The TikTok feed serves the ARCHIVED TikTok corpus — exactly what the spytrend.com /ads TikTok tab shows — and pagination carries has_more/next_cursor plus total with total_status (exact unless ttads marks the count estimated). With source=tiktok rows are TikTok webmaster CLUSTERS (business-id rollup — the same entity the spytrend.com /webmaster TikTok tab shows; a different id space from ttads domain clusters). Honored filters: query (name/domain/cabinet legal names), domain, countries (+min_geo_share), ai_category (dominant category), min_total_ads, min_active_ads, date_from/date_to, sort_by=total_ads|active_ads|created_at|relevance, limit (default 10, server caps at 100 for TikTok). TikTok-only filter has_funder=true keeps only clusters with an EXTERNAL 'paid for by' sponsor. Meta-only lookups (pixel_id/page_id/resolved_ip, languages/platforms/creative_format, status_today, ai_subcategory, min_geo_share without countries) are REJECTED, not ignored. TikTok has no status-checker: active means 'shown within the last 30 days'.
