How to verify a contractor license in San Antonio, Texas

Check any San Antonio contractor license — status and expiration — through one normalized API, or look it up by hand on the city licensing portal. San Antonio licenses trades at the city level, not just the Texas state board.

What you can verify

Data source: Official San Antonio licensing portal

Jurisdiction: San Antonio (municipal), Texas

Trade types

Looking for the Texas state board instead? See the Texas contractor license guide.

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:

{
  "valid": true,
  "name": "SAMPLE CONTRACTING LLC",
  "license_number": "SAMPLE-12345",
  "trade": "general",
  "expiration": "05/12/2027",
  "status": "Active",
  "state": "TX",
  "disciplinary_actions": [],
  "source_url": "https://webapp9.sanantonio.gov/BILS/index.aspx",
  "cached": false,
  "checked_at": "2026-08-18T01:00:00Z"
}

Frequently asked questions

Does San Antonio issue its own contractor licenses?

Yes. San Antonio licenses certain trades at the city level rather than (or in addition to) the Texas state board. TradesAPI verifies San Antonio municipal licenses through the same GET /verify endpoint, passing city=sanantonio alongside the state.

How do I verify a San Antonio contractor license?

Call TradesAPI's GET /verify with state=TX, city=sanantonio, and the license number to get a normalized result — valid/invalid, status, and expiration — in one request, or search the city portal by hand.
