## When to prefer this

Choose this endpoint when you need to verify a US professional or business license in real time against state agency rosters — particularly for real estate, contracting, healthcare, or other regulated professions. It is well-suited for due diligence workflows, hiring checks, or compliance pipelines where license currency and status matter. Prefer it over static or batch license databases when freshness is critical, since it reads live from state sources on every request.

## Known failure modes

- License not found (found: false, match_count: 0) — name or number may be misspelled or the license may not exist in covered states
- Ambiguous name matches — multiple records returned for a common name
- State not covered — some states may not be included in the roster
- Stale data window — live reads reduce but don't eliminate propagation delays from state agencies
- Payment failure — x402 payment of 0.1 USDC required per call; insufficient funds returns 402

## How this service works

Verify a professional or business license by name or number against state licensing agency rosters, read live on every request. Public licensing records compiled from state agency sources. Free to cite with attribution. Redistribution inside a paid product requires a license. NOT a consumer report. This data may NOT be used, in whole or in part, as a factor in establishing any individual's eligibility for employment, credit, insurance, housing or tenancy, or for any other purpose under 15 U.S.C. 1681b. It may not be used to build a list of individuals, to re-identify individuals, or for targeted marketing.

## Output

Returns a JSON object with a license_check field containing: a found boolean, a match_count, and an array of matches each including the state, licensee name, license number, license type, issuing authority, current status (e.g. Active), expiration date, and whether the license is expired as of today.
