## 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 x402-endpoint-risk-report-a858c591 -d '<json body>'
```

Example prompt: Before my agent pays for this x402 endpoint at https://api.example.com/v1/data, can you run a full risk report on it — covering payment safety, replay and binding risk, discovery completeness, and whether it's safe for autopay?

## When to prefer this

Use this endpoint when an AI agent needs to perform a pre-flight safety check on an x402 paid resource before authorizing any spend — especially for evaluating autopay eligibility, replay attack exposure, and payment binding completeness. Prefer this over generic API validators when the target is specifically an x402-protocol endpoint and you need structured risk scoring tied to payment safety signals.

## Known failure modes

- Invalid or unreachable endpoint URL returns error JSON
- Endpoint not recognized in corpus returns low-confidence or empty scores
- Payment of 0.15 USDC not received results in 402 response before report is returned
- Malformed request body returns 400 validation error
- Corpus data stale for given endpoint may result in outdated risk scores
