Search sex offender records

Search the national sex offender registry by name, address, zip code, GPS coordinates, or free-text query. For quick demos, GET with the key query parameter remains supported. For production, prefer POST with X-API-Key or Authorization: Bearer and JSON body fields. Send optional X-Request-Id for customer-side request correlation.
