What it does
License Proof checks a professional license (nurse, physician, engineer, contractor, attorney, real estate and more) by querying official licensing-authority publications live. Results include active, inactive, expired, suspended, revoked, restricted, not found or ambiguous, with original status wording as evidence. Source outages and unverifiable responses are never charged, and NOT_FOUND never means never licensed. Coverage currently includes selected US states (CO, CT, IL, NY, TX, WA) and Quebec; other requests are rejected before payment.
Use cases
- verify a contractor's license
- check a nurse or physician license status
- confirm a real-estate license before hiring
