Massachusetts also supports name search — when you only have a contractor's name, the /search endpoint returns every matching license with full metadata.

One call. The whole picture.

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

GET /verify?state=MA&license=SAMPLE-12345&trade=general
{
  "valid": true,
  "name": "SAMPLE CONTRACTING LLC",
  "license_number": "SAMPLE-12345",
  "trade": "general",
  "expiration": "05/12/2027",
  "status": "Active",
  "state": "MA",
  "disciplinary_actions": [],
  "source_url": "https://madpl.mylicense.com/Verification/",
  "cached": false,
  "checked_at": "2026-06-22T05:14:00Z"
}
