  Looks up a contractor's public credential in indexed state and local licensing records. Licenses, registrations and bond records mean different things. Each record carries a credential object (kind, label, note): kind is license, registration, business_license or bond when the source makes that clear; otherwise it is the generic "credential", and the note says what to verify with the issuing agency. The set of covered jurisdictions changes as sources are added, so this description does not list it. Inputs: a record number (license) or business name, with optional jurisdiction and exact listed city, or an entity_id from an earlier result, which selects that one record. Results: match (the credential record with its status and provenance); candidates (several records fit; each page holds up to 20 rows, total_candidates is the full count, offset pages through the rest, and entity_id selects one; a field with the same value on every row of a page is given once, in same_for_all_rows, and each row's entity block omits what the row already states); no_match_in_index (the index holds no record for that input, which does not mean the contractor is unlicensed; for a search across all jurisdictions, the message states how many covered jurisdictions were searched); or jurisdiction_not_covered (the requested jurisdiction is outside the index, with an official pointer URL where one is on file; the response message states exactly what the link is, or that none is on file, and for some jurisdictions the link is a consumer-protection or licensing-board page, not a license lookup).
