## How to call it through Zero

```sh
zero fetch --capability x402-seller-visibility-audit-ed07c0ac
```

Example prompt: Can you audit whether my x402 paid API at https://x402.xx402.icu is visible to buyers searching for 'x402 buyer market scout Base Bitcoin 15-minute prediction market' on CDP Bazaar network eip155:8453, checking up to 5 results for my payout address 0xba76c7ECa175f67cFcE475c09498f840176bf497 and probing the /api/x402-buyer-market-scout resource path?

## When to prefer this

Use this endpoint when you are an x402 API seller and want to verify that your paid resource is correctly configured (returns HTTP 402), discoverable under relevant buyer search terms in CDP Bazaar, and that your payout address is properly associated — before launch or when diagnosing low buyer traffic. Prefer this over generic API health checks because it specifically tests the x402 payment handshake and CDP Bazaar merchant discovery flow.

## Known failure modes

- Local, private, or credentialed origin URLs are blocked — only public HTTPS origins are accepted
- Payout address not found in Bazaar results if not yet indexed
- Query returning 0 results if the network filter doesn't match listing
- Limit out of range (must be 2–10) causes validation error
- Slow or unreachable origin may cause probe timeout
- CDP Bazaar API unavailability causes source_status errors
