One call. State and city licenses, same schema.

The /verify response is identical in shape whether the license is issued by a state board or a city — add the city parameter and your integration code stays the same:

GET /verify?state=CA&city=losangeles&license=SAMPLE-12345&trade=building_inspector

{
  "valid": true,
  "name": "SAMPLE CONTRACTING LLC",
  "license_number": "SAMPLE-12345",
  "trade": "building_inspector",
  "expiration": "05/12/2027",
  "status": "Active",
  "state": "CA",
  "disciplinary_actions": [],
  "source_url": "https://ladbsservices2.lacity.org/LADBSRoster",
  "cached": false,
  "checked_at": "2026-08-01T07:00:00Z"
}
