Tools

• find_shop

  Search merchants/shops by free-text query (name or domain fragment), optionally filtered by country (ISO 3166-1 alpha-2, e.g. "DE"). 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. If many shops match, grouping by country or category keeps the list scannable.

• get_shipping_policy

  What a shop STATES about its own shipping: which destinations it names, the delivery time it claims, and any free-shipping threshold — plus the date that statement was last checked and where it was read (policy_page or structured_data). 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.

  shallow
• get_shop

  Fetch a single merchant/shop by id or domain (public view). Returns "shop not found" for shops still under internal review, identical to a genuinely unknown domain — reviewers cannot be distinguished from typos. The offers array is present for schema stability but empty until merchant offers are ingested (Offer table measured empty on 2026-07-30).

  shallow
• get_trust

  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.

  shallow
• list_coupons

  List currently visible discount codes/coupons, optionally filtered by shop_domain (e.g. "otto.de"). Only publicly displayable coupons are returned — internal/candidate-shop or policy-suppressed codes are excluded, and EXPIRED codes are never returned (a code whose valid_until has passed is withheld). 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; including the shop domain and the expiry avoids sending users to codes that will not apply for them.

  shallow
• report_code

  Record that a specific shop_domain + code (coupon) pair was tried and the outcome (invalid, expired, store_specific, or worked). This is a write: it appends one new report row and never deletes or overwrites existing data — it does not change what list_coupons returns immediately, since reports feed aggregate signals over time. No PII is accepted or stored (note text is scrubbed).

  shallow
• report_issue

  N5 (2026-08-23): Record a shop-level or data-fact issue as one fixed, documented reason (no free text). subject_type "shop": unreachable | no_longer_exists | info_outdated | wrong_category | wrong_name_or_domain. subject_type "fact": shipping_cost | return_period | payment_methods | evidence_broken. Same write semantics as report_code: appends one report row, never changes delivered data directly, only queues a re-check subject to per-source dedup.
