## How to call it through Zero

```sh
zero fetch --capability license-check-4b15df64
```

Example prompt: Can you verify whether Ben Helstein in Texas holds an active real estate broker license? His license number is 727703-B — I need to confirm it's current before we move forward.

## When to prefer this

Use this endpoint when you need real-time verification of a professional or business license against official state agency records, particularly for contractor vetting, vendor onboarding, compliance checks, or pre-hire credential verification. It is preferable to manual lookups on individual state websites and suitable when you need a single API call that checks live rosters rather than cached or batch-compiled databases.

## Known failure modes

- License not found in state roster — returns found: false with match_count of 0
- Ambiguous name match — multiple records returned requiring further filtering
- State agency data temporarily unavailable — may return incomplete results
- Invalid or malformed license number — no matches returned
- Name spelling variations may cause missed matches

## 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 indicating whether a matching license was found, along with details for each match including the state, licensee name, license number, license type, issuing authority, current status (Active/Inactive/etc.), expiration date, and a boolean indicating if the license is expired as of today.
