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.
Example use cases
Contractor vetting before hiring
“Before I hire this contractor, can you verify that John Martinez with license number CR-123456 actually has an active contractor license in California?”
Real estate agent credential check
“I'm about to close on a house — can you confirm that my real estate agent, Sarah Collins, has a current, active broker license in Florida?”
Healthcare provider license verification
“Can you look up whether Dr. Emily Huang is a licensed physician in New York State and whether her license is still valid?”
Technical details
Endpoint
GEThttps://license.ccbaydata.com/v1/licenseWhen to prefer
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.
Side effects
- 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
