How this service works
GovChain turns SAM.gov into pursue-ready intelligence: AI fit-scoring, auto-drafted capability statements, and an immutable on-chain public datalog for Made-in-USA and federal compliance.
Output
Returns a JSON object containing: verified (boolean), authenticityScore (0–1 numeric confidence), subject identifier, settlement details (payer address, transaction hash, trustless flag, atomic USDC amount paid), and a human-readable note about the registry lookup result.
Example use cases
Pre-bid seal verification for federal RFP
“Before we submit our proposal on SAM.gov, can you verify seal ID 'GOV-SEAL-7723' with serial 'SN-10042' and product ID 'PROD-8801' to confirm our authenticity score meets federal compliance requirements?”
Made-in-USA supplier validation
“I need to validate that supplier product 'PROD-5510' with serial 'SN-30091' qualifies as Made-in-USA — can you run it through GovChain and show me the verification result and on-chain settlement details?”
Immutable compliance log for audit trail
“Log a provenance record for seal ID 'SEAL-AUDIT-2025-003', serial 'SN-77654', product 'PROD-9912' so we have an immutable on-chain entry we can reference during a federal contract audit.”
Technical details
Endpoint
POSThttps://govchain.us/api/x402?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need cryptographically-anchored provenance logging combined with AI-driven authenticity scoring for federal procurement compliance — specifically for Made-in-USA validation, SAM.gov bid preparation, or building an immutable audit trail for government contract submissions. Prefer over generic document verification tools when the use case involves federal supplier credentials, seal authentication, or blockchain-backed compliance records.
Side effects
- Unrecognized seal ID returns verified: false with authenticityScore 0
- Missing required body fields (type, method, bodyType, body) causes validation error
- Invalid method enum value (not POST/PUT/PATCH) causes schema rejection
- On-chain settlement failure may return txHash: 0x with trustless flag still set
- Registry lookup not bound on edge paths returns note but no registry data
