Complete Criminal Checks
Complete Criminal Checks exposes a single search endpoint that queries U.S. arrest records, sex-offender registries, jail/inmate rosters, and most-wanted lists across all 50 states plus Puerto Rico, returning one merged JSON payload per name search across the four data feeds. Requests are authenticated with an X-API-Key header and billed per lookup against a prepaid credit balance. New accounts start with 25 free credits, enough to test all four feeds before paying for further searches.
