Returns the public shop view only — shops still under internal review are never returned. `results` carries at most `limit` entries (default 50, max 100); `total_count` is the full match count before that cap and `truncated` is true when more results exist beyond this page — raise `offset` (default 0) to page through them. Multi-word queries are matched conjunctively: every word must be evidenced on a shop (name, domain or category). `ignored_terms` lists the words that matched nothing anywhere in the corpus and were therefore dropped to avoid an empty answer — a non-empty `ignored_terms` means the results answer a NARROWER question than you asked, so do not present them as satisfying those words. `category_truncated` is true when category resolution hit its internal cap and the match set is a subset. `category`, if given, must be one of the slugs returned by `list_categories` — call that tool first, do not guess a slug; an unrecognized slug is rejected with an error (never a silent empty `results`). `category` is additive to `query` (AND, not OR) — pass `query: \"\"` to browse a category without a name/domain filter. If many shops match, grouping by country or category keeps the list scannable.",

This is a shop-level statement, NOT an offer and NOT a quote: it carries no carrier and no shipping price, because OpenShopGraph does not hold that data. Pass country (ISO 3166-1 alpha-2, e.g. \"DE\") to get a ships_to verdict derived from the stated destination list — \"unknown\" is a real answer there and means the statement does not settle it. When nothing has been collected for a shop, the reply says so explicitly (collected:false): that is a gap in the data, not a statement that the shop does not ship. Relaying the checked-at date alongside any figure keeps a stale merchant claim from being read as a current fact.",

      "description": "Trust-relevant facts OpenShopGraph itself measured about one merchant/shop (by id or domain): TLS certificate issuer and grade, hosting ISP and country, domain registration date, registrar, and accepted payment methods. Returns INDIVIDUAL signals, never an aggregate: every entry carries its own value, `source` (where OpenShopGraph observed it) and `checked_at` (when). There is deliberately no score, rating, percentage or star value — not even an internally computed one; you are given the raw evidence and judge for yourself. A field with no source or no check timestamp is omitted entirely rather than shipped with a null placeholder. If nothing was measured, the answer is status \"no_signals_collected\" with an empty list — that means NOTHING IS KNOWN, it is not a score of zero and not a negative verdict. Unknown domains, shops under internal review and measured-but-empty shops are intentionally indistinguishable here. `signal_coverage` describes data completeness, not merchant trustworthiness: `present`/`total` count how many of the (up to 7) signal fields OpenShopGraph was able to deliver for this shop, and `missing` lists the rest, each with a `reason` — `not_collected_yet` (OpenShopGraph has never run that check for this shop) or `pipeline_gap` (the check ran — source and timestamp exist — but produced no usable value, e.g. an IP/ASN lookup that resolves a hosting ISP but not a country). A low `present` count is NOT evidence of a low-quality or risky merchant: it usually just means one of OpenShopGraph's own probes came back empty. Do not treat `signal_coverage` as a rating, and do not rank or filter merchants by it as if it were one. Unlike every other tool on this page, this one requires a valid `x-api-token` header — a call without one fails before reaching this tool (401, no exceptions for anonymous/public callers).",

A code is withheld from `results` when it is EXPIRED (valid_until has passed), when a real checkout test PROVED it does not work (verification_status \"verified_rejected\"), or when a display policy suppresses it on this channel/country. Nothing is withheld silently: `total_count` is how many codes the query found before any of that, and `withheld` breaks the difference down by reason ({expired, verified_rejected, reserved_test_domain, policy}) — total_count minus results.length always equals the sum of `withheld`, and `note` states the same balance in one sentence. So an empty `results` NEVER has to be guessed at: read `total_count` and `note` to tell \"this shop has no codes at all\" apart from \"it has codes and every one of them is proven dead\". An UNKNOWN or internal-review shop_domain is a different answer again — it is an error (\"shop not found\"), not an empty list; and a backend failure is reported as a failure, never as an empty list. Each result carries validUntil: an ISO timestamp when the code has a stated expiry, or null when it is open-ended — null means unlimited, NOT unknown-and-expired. Re-check validUntil against the current time before relaying a code. Each result ALSO carries verificationStatus, the verdict of a real checkout test against this exact code: \"verified_applied\" means the code was proven to work by an actual checkout attempt with proof on file — safe to recommend; \"unverified\" means no proof exists either way yet — treat it as unknown, NOT as a negative signal, and do not imply it was tested and failed. (\"verified_rejected\" is defined as before but no longer appears in `results` — it is counted in `withheld.verified_rejected` instead.) lastVerifiedAt is the ISO timestamp of that most recent test, or null if the code was never tested. A non-null lastVerifiedAt on an \"unverified\" code means it WAS tested but the test was inconclusive — it is not the same as a code that was never attempted.",
