City-level licensing in New York

Some New York trades are licensed by the city, not the state board. We also cover municipal licensing in New York City under the same normalized schema and the same /verify call.

One call. The whole picture.

The /verify response is identical in shape across every state, so your integration code never changes per jurisdiction:

{
  "valid": true,
  "name": "SAMPLE CONTRACTING LLC",
  "license_number": "SAMPLE-12345",
  "trade": "home_inspection",
  "expiration": "05/12/2027",
  "status": "Active",
  "state": "NY",
  "disciplinary_actions": [],
  "source_url": "https://appext20.dos.ny.gov/lcns_public/chk_load",
  "cached": false,
  "checked_at": "2026-06-22T05:14:00Z"
}
