How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with an audit score (0–100), an audit level label (e.g. 'excellent'), and a list of gaps identifying missing or misconfigured parts of the x402 implementation. Also includes the tool name used.
Example use cases
Pre-launch x402 compliance check
“Before I go live, can you audit https://api.myapp.com/premium-endpoint and tell me if my x402 implementation is correct and what gaps I need to fix? Use a 10 second timeout.”
Third-party API vetting for agents
“I'm thinking of integrating https://partner.service.io/api/v1/data into my agent — can you audit it to see how well it implements x402 and whether the payment layer is solid? Give it up to 15 seconds to respond.”
Debugging a failing x402 payment flow
“My x402 server at https://commerce.mycompany.com/api/invoice keeps failing — can you run an audit on it with a 5 second timeout and tell me what the score is and what's broken?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/server-audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to verify that a specific URL correctly implements the x402 pay-per-result payment protocol — especially before integrating a third-party x402 API into an agent workflow, or when debugging your own x402 server. It is purpose-built for x402 compliance checking, unlike generic HTTP probing or uptime monitoring tools.
Side effects
- URL unreachable or returns non-402 response — audit may fail or return low score
- Timeout exceeded (max 15s) — request times out and no result is returned
- Invalid URL format — request rejected with validation error
- Target server does not implement x402 at all — gaps list will be extensive and score will be low
