Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-x402-server-audit-0f948cc3 -d '<json body>'
```

Example prompt: Can you audit https://myservice.example.com/api/payment to check how well it implements x402, with a 10 second timeout? I want to know the audit score, level, and any gaps.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
