## 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-bazaar-rank-in-evidence-deep-e9b88055
```

Example prompt: Show me the top x402 evidence-tagged services ranked by paying wallets over the last 30 days — I want the live bazaar snapshot with call counts and prices.

## When to prefer this

Choose this endpoint when you specifically need ranked discovery of x402 services tagged 'evidence', scored by authentic 30-day on-chain activity (calls and paying wallets), with a verifiable receipt (snapshot hash + scoring revision). Prefer it over generic API directories when you need provably real usage metrics rather than self-reported stats, and when you're operating within the x402 payment protocol ecosystem.

## Known failure modes

- No services match the evidence tag — returns empty services array with count 0
- Snapshot index stale or unavailable — may return outdated generatedAt timestamp
- Rate limiting or payment failure (x402 $0.04 USDC required per call) — returns 402 Payment Required
- Worker timeout on large index scans — partial results or 5xx error
- Invalid or missing query parameters — returns 400 Bad Request
