lookup_siteread-onlyFree. The last dated verdict for a website, if it was ever checked and listed: verdict, score, date and badge. An unknown site is a normal answer (known: false), not an error. To get a fresh check, buy one (see get_pricing).
get_pricingread-onlyEvery product for sale — the check (one payment, one check) and the catalog snapshot — with its price, the query parameters the paid request needs, and the exact x402 v2 payment requirements. Call this before buying.
get_docsread-onlyThe whole machine guide as JSON: quickstart, what each verdict means, packs, the rules every check runs, and every public route.
get_service_statusread-onlyWhether the service is selling right now, in which mode and on which network, and if not, why not. This is configuration, not liveness: the health endpoint is at /health.
