Trust receipt by exactly one identifier: domain, phone, license or address

E.164 or 10-digit US number; punctuation ignored.

Licence number as printed by the register. Case, a leading # and the license: or lic- prefix of a record id are ignored; on a domain-keyed market so is punctuation. 400 bad_license when nothing but punctuation is left, when more than 32 letters and digits are, or for a control character or a letter or digit outside ASCII.

Street address, as the business publishes it or as the register prints it. The street line before the first comma decides: city, state, ZIP and a unit (floor, suite, storefront) are set aside, and a number inside a registered range (1000-1012) matches it. Case, punctuation and common abbreviations (N, St, Ave, Rd, Blvd) are normalised; a missing directional or suffix is never guessed. Several businesses at one address answer 300 with candidates.

Market slug from /v1/markets. Without it a lookup starts on the primary market and falls through to every other market by domain or licence; with it the lookup stays on that record. Without it, a market that cannot be read is skipped while the others are asked, and a business none of them holds answers as a named market that cannot be read does (record_unavailable), not as not on the record. Unknown slugs answer 404 unknown_market with the list.

receipt (default) answers the full TrustReceipt. check answers the compact TrustCheck: the same receipt, projected to matched, the dated facts with their sources, the fields not published and the first expiry. Unknown values answer 400 unknown_view.

Optional self-declared consumer name, e.g. my-booking-agent. Never gates or changes the response. Used to count distinct integrations without a key, a cookie or an IP. Sending it adds only that string to what we store.
