How this service works
Machine-buyable infrastructure for autonomous agents: API cost routing, margin optimization, funding-rate data, webpage extraction, result verification, spend controls, retry planning, state, tender search and GitHub bounty intelligence.
Output
Returns a ranked list of audited sellers, each with a numeric conformance score (0-100), a decision label (conformant/review/blocked), an array of findings with severity codes, the seller's origin and pay-to address, and summary counts. Also includes an audit_sha256 fingerprint and a limitations disclaimer clarifying the audit is deterministic and metadata-only.
Example use cases
Pre-routing seller vetting
“Before I start routing any agent spend through these three sellers, can you audit their x402 metadata and tell me which ones are conformant, which need review, and which are blocked?”
Settlement receipt investigation
“I'm seeing unconfirmed settlement receipts from seller-a at https://seller.example — can you run a conformance audit and show me exactly what findings and severity codes are flagged?”
Marketplace seller ranking
“I have a list of candidate sellers for my agent marketplace — can you score and rank them all by x402 conformance so I can prioritize the highest-quality ones?”
Technical details
Endpoint
POSThttps://bounty-engineer-x402-prod.onrender.com/v1/seller-conformance-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic, metadata-level compliance check on x402 seller records before routing agent spend or admitting sellers to a marketplace — not when you need live on-chain settlement verification or real fund movement.
Side effects
- Malformed seller metadata returns validation errors rather than scores
- Missing required fields (origin, pay_to, network) cause audit to fail
- Audit is deterministic on supplied data only — does not independently fetch or verify live seller behavior
- Network identifiers in unsupported formats may produce unscored results
- Service unavailability on Render hosting may return 5xx errors
