How this service works
Stateless, source-cited public-data checks for agents.
Output
Returns a JSON object containing the UEI queried, whether the entity was found ('found' or not), the registration status code (e.g. 'A' for active), the registration expiration date, the source (SAM.gov Entity Management API), and the service name. The response is stateless and source-cited for audit purposes.
Example use cases
Pre-award contractor eligibility check
“Before we issue this purchase order, can you verify that vendor UEI JK3L4M5N6P7Q is currently registered and active in SAM.gov?”
Automated procurement compliance gate
“Run a SAM.gov registration check on UEI AB1CD2EF3GH4 and tell me if they're active and when their registration expires — we need to know before onboarding them.”
Expired registration alert for existing vendor
“Can you pull the SAM.gov status for our current supplier with UEI XY9ZA8BC7DE6 and confirm whether their registration is still valid or has lapsed?”

Endpoint
POSThttps://api.brightonhilyard.com/api/sam/registration?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a stateless, source-cited, per-call check of a specific entity's SAM.gov registration status without maintaining your own integration with the SAM.gov API. Ideal for agents performing pre-award compliance checks, onboarding workflows, or ad hoc vendor verification where auditability (source citation) matters. Prefer this over building a direct SAM.gov API integration when you need a lightweight, pay-per-call solution with no API key management.
Side effects
- UEI not found in SAM.gov — returns result indicating entity not found
- Invalid UEI format (not 12 characters) — likely returns a validation error
- SAM.gov API unavailable or rate-limited — upstream timeout or error response
- Expired or deregistered entity — found but with non-active status code
- Payment failure via x402 — call not processed if USDC payment is not completed
