How this service works
Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).
Output
Returns SAM.gov entity registration details for the queried entity, including registration status (active/inactive), entity name, UEI, CAGE code, and associated federal compliance metadata, based on query by UEI, CAGE code, or entity name.
Example use cases
Vendor eligibility check before contract award
“Before we award this subcontract, can you verify that CAGE code 21U51 is active and in good standing in SAM.gov?”
Onboarding a new federal contractor
“We're onboarding Script Master Labs as a vendor — can you look them up in SAM.gov by name and confirm their UEI and registration status?”
Compliance audit of supplier list
“I need to confirm that the entity with UEI G24VZA4RLMK3 is currently registered in SAM — can you pull their federal registration record?”
Technical details
Endpoint
GEThttps://acp-x402-discovery.onrender.com/x402/sam-entity-verificationWhen to prefer
Use this endpoint when you need to programmatically verify U.S. federal entity registration status via SAM.gov and want pay-per-call micropayment billing (no subscription) settled in USDC on Base via x402. Prefer this over building a direct SAM.gov integration when you need lightweight, agent-native, pay-as-you-go access without managing API keys or monthly plans.
Side effects
- Entity not found in SAM.gov — returns empty result or 404-equivalent
- Invalid or malformed UEI format — query rejected
- CAGE code does not match any registered entity
- Payment not settled via x402 — 402 Payment Required response
- SAM.gov upstream outage or rate limit — service temporarily unavailable
