How this service works
Machine-discoverable services AI agents can call and purchase autonomously.
Output
Returns the status and details of the contractor license associated with the provided license number, including whether it is active, expired, or invalid, and potentially contractor name, license type, and expiration date.
Example use cases
Pre-hire contractor credential check
“I'm about to hire a plumber and they gave me license number PL-998821 — can you verify that it's a valid, active license before I pay them the deposit?”
Real estate due diligence on renovation work
“The seller says the kitchen renovation was done by a licensed contractor with license 45872-B. Can you check if that license is legitimate and active?”
Automated vendor onboarding compliance
“We have a new subcontractor applying to work on our job site — their license number is TX-GC-20045. Please verify it's valid so we can clear them for onboarding.”
Technical details
Endpoint
POSThttps://api.aisoup.net/contractor-check/v1/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, automated check of a contractor's license status by license number, especially before hiring, onboarding, or approving payment to a contractor. Prefer this over manual searches of state licensing boards when you need programmatic, agent-driven validation.
Side effects
- License number not found — returns error or empty result if the number does not exist in the registry
- Invalid format — if the license number does not match expected format, the API may reject the request
- Service unavailability — the underlying licensing database may be temporarily unreachable
- Ambiguous results — some license numbers may match multiple records or jurisdictions
