Search online stores and their traffic

search_shops
Read-only

Search ONLINE STORES — the same catalogue as the website's /shops page (not every domain: general sites such as google.com or youtube.com are not in it). Each row carries traffic, commerce and advertising intelligence for one store domain. Shops advertising now in a country ("shops with fresh/active ads in Mexico"): country= + has_ads=true (only shops with ACTIVE ads now; add min_ads=N for a floor) + sort_by=ads — do NOT use search_ads for this; there is no separate freshness-window filter. visits is a MONTHLY estimate for traffic_as_of (not live traffic); fetched_at is ingestion time. Judge every estimate using traffic_quality, traffic_confidence, traffic_is_small, traffic_is_data_from_ga, traffic_data_status and history. traffic_paid_share is display + paid-search + paid-social share; trust it only when traffic_sources_available=true. visits_growth_pct is latest-vs-previous month PERCENT; min_growth and sort_by=growth only return growth_qualified rows (current cohort, contiguous 3-month window, previous month >=10k, non-small estimate, confidence >=0.60). category is an estimated SITE category and may be missing/wrong; ai_category is Spytrend's AD category and is preferred for ad-market discovery. created_from/to filter domain_created: best available registration date of the REGISTRABLE ROOT, not product/subdomain launch or Spytrend first-seen. The ClickHouse row does not retain whether that date came from the preferred registry lookup or the legacy fallback. traffic_start_max compares the current estimate with the MAXIMUM of both preceding complete months and excludes stale/low-quality windows; combine with traffic_end_min. ads_monthly counts ads first observed by Spytrend (first_parsed_date), and each point has is_complete=false for the open current month. fb_signal is correlation_only, not causal attribution; honest statuses are correlated_growth, ad_growth_ahead, ad_growth_flat_traffic, ad_growth_declining_traffic, traffic_growth_without_fb_growth, stable_or_mixed and insufficient_signal. sort_by=relevance REQUIRES ai_category and is rejected otherwise. Sorts: visits/revenue/growth/ads/rank/backlinks/ai_traffic/products/fb_score/per_ad/relevance; sort_by=ads orders by the number of ACTIVE ads now (active_ads), not by total_ads — never describe it as 'sorted by total number of ads'; sort_by=revenue and min_revenue use website_value — the estimated VALUE of the site in USD, NOT revenue, and outliers with tiny traffic are possible. country/country_exclude match the shop's MAIN visitor country (top_country). An empty page carries a note explaining why. product_count is the number of products shown on the website shop card (the larger of the crawler counter and the real catalog size products_total). a separate legacy snapshot is kept alongside; never substitute its similarly named traffic fields for the primary visits/traffic_as_of contract. Returns total, has_more and offset; total is the exact number of matching stores and has_more is true whenever total > offset+rows. FREE SAMPLE: without a Shops subscription the catalogue returns a short preview (a few rows) whatever the limit and deeper offsets come back empty — the result then carries a note "Free sample: N of TOTAL…" and params.normalized limit (requested→delivered); say it is a sample of TOTAL stores, never that only N exist. Use get_shop for the full source payload. Saving shops is free. 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 MCP credit per DELIVERED result from your plan balance (free starter: 500 MCP credits lifetime; paid plans: 40,000/month; short pages auto-refund — you pay only for results you receive). Default page is 20 results = 20 MCP credits; 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. PRICING: price × number of filters set (min 1), on paid plans ×1 after 500 MCP credits/month; one-time consent via accept_pricing_terms; before calling, get the maximum debit from estimate_cost (free) and tell the user.

Input Schema

NameRequiredDescriptionDefault
qNosubstring search on the normalized domain; URLs are normalized to their host
limitNomax results (default 20, at most 200; each delivered result costs 1 MCP credit). Without a Shops subscription the catalogue answers a free sample of a few rows whatever the limit: params.normalized then reports limit as requested→delivered, note says the page is a free sample and has_more stays true while total exceeds offset+rows.
savedNosaved scope selector. Use saved=all to restrict results to shops saved in ANY favourites folder.
offsetNopagination offset (0-based)
pixelsNocomma-separated pixel identifiers to filter by
countryNoISO-2 country code (any case; unknown codes are rejected) — keep only shops whose MAIN visitor country (top_country) is this country, NOT every shop with some traffic there. For small sites top_country can come from the site's country ranking instead of visitor shares, so a small shop whose visitors mostly come from another country may be listed under the wrong one
has_adsNotrue = only shops with ACTIVE ads now (the site's 'Has active ads' chip)
min_adsNominimum number of ads
socialsNocomma-separated social-media handle filters
sort_byNoorder by: visits (default), revenue (= website_value, the estimated site VALUE in USD, not revenue), growth, ads (= number of ACTIVE ads now, active_ads — not total_ads), rank, backlinks, ai_traffic, products, fb_score, per_ad or relevance; relevance REQUIRES ai_category and is rejected without it
categoryNoestimated site-category filter; may be missing or misclassified, so prefer ai_category for ad-market discovery
platformNocommerce platform the site runs on: Shopify, WooCommerce, WordPress, Wix, Squarespace, Magento, PrestaShop or BigCommerce
fb_statusNoobserved ads/traffic relationship: correlated_growth, ad_growth_ahead, ad_growth_flat_traffic, ad_growth_declining_traffic, traffic_growth_without_fb_growth, stable_or_mixed or insufficient_signal; correlation only
folder_idNorestrict results to shops saved in this favourites folder UUID. Mirrors the /shops folder view.
created_toNoregistrable-root registration date on/before YYYY-MM-DD; NOT product/subdomain launch; per-row RDAP/WHOIS-vs-legacy provenance is unavailable
max_bounceNomaximum bounce rate in PERCENT (0-100) — max_bounce=30 keeps only sticky sites, the reason this control exists. The server converts it to the fraction the column stores.
max_growthNoupper end of the traffic-growth range (percent). The /shops panel has BOTH ends; pair it with min_growth for a band such as 10..50.
max_per_adNomaximum visits-per-ad efficiency
max_visitsNomaximum monthly visits
min_bounceNominimum bounce rate in PERCENT (0-100), matching the visible /shops bounce slider — min_bounce=70 keeps only high-bounce sites. The server converts it to the fraction the column stores.
min_growthNominimum latest-vs-previous monthly visits growth PERCENT; only current-cohort growth_qualified rows pass (contiguous 3 months, previous >=10k, non-small, confidence >=0.60)
min_per_adNominimum visits-per-ad efficiency (traffic / active ads)
min_visitsNominimum monthly visits
sort_orderNosort direction: asc or desc (default desc)
ai_categoryNoAI category slug the shop's ads belong to (e.g. ecommerce_and_retail)
min_revenueNominimum site value estimate in USD (website_value — the estimated VALUE of the site, not monthly revenue; the row field is website_value)
shopify_appNoShopify app slug filter (shops using this app)
created_fromNoregistrable-root registration date on/after YYYY-MM-DD; NOT product/subdomain launch or Spytrend first-seen; per-row RDAP/WHOIS-vs-legacy provenance is unavailable
has_productsNotrue = only shops with a product catalog in our database
min_productsNominimum number of catalogued products
shopify_planNoShopify plan name filter (e.g. Basic, Shopify, Advanced)
min_backlinksNominimum total backlinks
shopify_themeNoShopify theme slug filter
has_ai_trafficNotrue = only shops receiving AI-referred traffic (ai_traffic_share > 0)
has_trustpilotNotrue = only shops with Trustpilot reviews
country_excludeNoISO-2 country code (any case) — drop shops whose MAIN visitor country (top_country) is this country
traffic_end_minNolatest monthly estimate at traffic_as_of is at least this value; combine with traffic_start_max
traffic_start_maxNomaximum allowed baseline traffic, where baseline=max(two complete months before traffic_as_of); stale, low-quality, incomplete and non-contiguous windows are excluded; combine with traffic_end_min
min_trustpilot_ratingNominimum Trustpilot rating (0-5)
exclude_infrastructureNodrop rows that are transit rather than an offer — link shorteners / link-in-bio, app stores and marketplaces, social networks and messengers, ad servers. Every row also carries surface_role (destination | redirect | store | social | adserver; absent for an ordinary merchant site) so you can filter yourself instead. NOTE: rows are dropped after the page is fetched, so an excluded page can return fewer than limit rows — page on has_more/offset, not on row count.

Output Schema

dataNo
metaNo
noteNo
errorNoPresent only when isError is true: machine-readable failure. The human explanation stays in content.
totalNo
offsetNo
paramsNoRequest parameter echo: applied = parameters that shaped this result; normalized = parameters rewritten before applying (alias, type coercion, resolved id); ignored = parameters that were accepted but NOT applied, with the reason.
has_moreNo
addon_hintsNoAdd-on modules that have additional data for objects of this result (no prices, no paid values). subscription_status=active: the account has the module — use its normal path. Do not push a purchase the user did not ask about.

TDQS

A4.2/5.0
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnly/openWorld/no-destruction, and the description adds substantial non-obvious behavior: per-result credit cost, free-sample preview caps, restricted pagination windows (total_status=restricted, plan_window_cutoff), and an empty page carrying an explanatory note. However it also spends a large share of its length on account-level concerns (quota balances, consent, concurrency admission, rate-limit error codes) that apply to many tools rather than this one, so the tool-specific behavioral signal is diluted.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness2/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Roughly 700 dense words with the actual filtering guidance interleaved among pricing, quota, rate-limit and concurrency paragraphs that repeat verbatim-style boilerplate rather than telling the caller anything about search_shops. Several clauses restate the schema (fb_signal status list, sort_by enumeration, created_from/to semantics) instead of adding to it, so the high-value routing sentences are buried.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 40-parameter open-world search with an output schema, the description still covers the things structured fields cannot: the free-sample distortion, the archive-window zero-means-nothing-in-window caveat, cost per delivered row, and the has_more/offset pagination contract. Nothing an agent needs to call or interpret results is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline is 3; the description earns above that by adding cross-parameter meaning the schema states only in isolation: sort_by=ads is active_ads not total_ads, country matches top_country (main visitor country) rather than any traffic, min_growth filters to growth_qualified rows, and traffic_start_max is meant to be paired with traffic_end_min.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Opens with a specific verb+resource and an explicit boundary: the /shops catalogue, not every domain (google.com, youtube.com excluded). It also names siblings it is not — 'do NOT use search_ads for this' and 'Use get_shop for the full source payload' — so an agent can route without opening another schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives an explicit recipe for a real task ('shops with fresh/active ads in Mexico': country + has_ads=true + sort_by=ads) and names the wrong tool to use. Also states a hard precondition (sort_by=relevance requires ai_category and is rejected otherwise) and where to go for detail (get_shop).

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
