How this service works
Agent-commerce trust/audit API for x402 challenge correctness, receipts, replay/context binding, failed payout triage, mandate readiness, and MCP/A2A discoverability.
Output
A JSON object containing a numeric score (0-100), the network (e.g. 'base'), product label, price in USD, timestamp, and an array of findings each with an item description, severity (high/medium/low), and a specific recommended fix action.
Example use cases
Example prompt
“Run an x402 launch audit on my API and give me a score plus a ranked list of concrete fixes — I want to know if my Bazaar indexing, paid-route gating, and facilitator calls are set up correctly.”
Technical details
Endpoint
GEThttps://x402.167-172-95-184.nip.io/audit/x402?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, scored diagnostic of an x402 integration specifically — covering Bazaar indexing readiness, paid-route gating correctness, facilitator call history, and buyer-agent copy quality. Prefer this over manual checklist review when you want machine-readable findings with severity rankings and actionable fixes.
Side effects
- Payment not received — returns HTTP 402 requiring USDC payment on Base via x402 protocol
- No settled facilitator call yet — audit may flag this as a high-severity finding rather than failing
- Ephemeral tunnel URL instability — the nip.io domain may be unreachable if the underlying IP changes
- Malformed payment header — x402 payment verification fails, returning 402 or 400
