Instructions excerpt

Free, neutral contractor-license checks from official state and local licensing records across dozens of US jurisdictions (the coverage endpoint and each check result state exactly what was and was not searched). Every finding carries provenance (source, snapshot date, artifact hash). CRITICAL honesty rule to relay: a no_match_in_index result is NEVER a determination that a business is unlicensed; licenses may be held under different names, other jurisdictions, or boards we do not cover.
