## 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-prices-dcbf4fe8
```

Example prompt: Show me the top 25 x402 services tagged with price data, ranked by number of unique paying wallets over the last 30 days — I want to see real usage numbers and the price per call for each one.

## When to prefer this

Choose this endpoint when you need a ranked, real-usage-backed leaderboard of x402 services specifically tagged with pricing metadata, with verifiable provenance (snapshot hash + scoring revision). Prefer it over generic x402 service lists when you need to filter to price-discoverable services and rank by economic activity (payers or calls) rather than arbitrary order. The receipt-based auditing makes it suitable for research or compliance contexts where snapshot integrity matters.

## Known failure modes

- No services match the 'prices' tag filter — returns empty array with count 0
- Snapshot index temporarily stale — generatedAt timestamp may lag real-time by up to the indexing window
- Payment of $0.008 USDC not included or invalid — returns 402 Payment Required
- Rate limiting on the Cloudflare Worker — returns 429 Too Many Requests
- Malformed query parameters — returns 400 Bad Request with error detail

## 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.

## Output

A JSON object containing a ranked array of up to N x402 services, each with name, network chain (EIP-155), 30-day call count, price in USD, resource URL, and 30-day unique payer count.
