## 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-data-08ac1c38
```

Example prompt: Show me the top 25 data services on the x402 marketplace right now, ranked by the number of paying wallets over the last 30 days.

## When to prefer this

Choose this endpoint when you need ranked, real-usage-validated discovery of x402 data services specifically — it provides verifiable 30-day call and payer counts rather than self-reported or static listings. Prefer it over generic API directories when you need to find what's actually being paid for on the x402 network right now, especially for the data category.

## Known failure modes

- No services indexed under 'data' tag returns empty services array
- Snapshot hash mismatch may indicate stale or inconsistent index
- Network errors from Cloudflare Workers edge may return 5xx
- Invalid or missing query parameters may return 400 with schema error
- Rate limiting may apply if called excessively without payment

## How this service works

Ranked discovery over the live x402 service market: every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision.
