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 x402station-io-6e085836 -d '<json body>'
```

Example prompt: Run a full provider audit on https://mypaymentapi.com/resource and issue a 30-day signed verification certificate for it — I want the tier rating, badge URL, and cert ID so I can display proof it's a legitimate x402 endpoint.

## When to prefer this

Use this endpoint when you need a signed, time-bounded (30-day) trust certificate for an x402 endpoint — not just a quick preflight check. Ideal for providers wanting to display verified badges, agents needing high-assurance trust signals before committing to a provider long-term, or marketplaces requiring audited listings. Prefer Preflight for cheap one-off checks ($0.001); use Verified ($1) when a formal audit record and certificate artifact are required.

## Known failure modes

- URL is unreachable or not an x402 endpoint — returns unverified status or error
- Insufficient USDC balance — payment fails and no certificate is issued
- Provider has no settlement history — tier may be low or unverifiable
- Invalid URL format — request rejected with validation error
- x402 endpoint returns unexpected response format — audit inconclusive

## How this service works

Independent risk-signal layer for x402 agentic commerce — endpoint evidence (decoy / zombie / price-trap / never-paid) before an agent authorizes payment.

## Output

Returns a certId (unique certificate identifier), verified boolean, tier (quality tier rating), and badgeUrl (embeddable badge image link), plus CDP-sourced settlement count and recency data about the audited provider.
