## 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-europe-discovery-f4750070
```

Example prompt: Pull up the top x402 services tagged Europe ranked by 30-day call volume and show me which ones have the most unique paying wallets this month.

## When to prefer this

Choose this endpoint when you need a geographically scoped (Europe) ranked view of live x402 micropayment services with real usage signals (call counts, unique paying wallets) rather than self-reported listings. Prefer it over generic API directories when you want verifiable, on-chain-activity-backed rankings with snapshot receipts for auditability. It is specifically suited for agents doing market research, competitive analysis, or service selection within the x402 ecosystem targeting European networks.

## Known failure modes

- No services indexed under the 'europe' tag returns an empty services array with count 0
- Worker cold-start latency may cause occasional slow responses
- Stale snapshot if the indexer hasn't refreshed within 30 days
- Payment of $0.008 USDC required per call; unpaid requests return HTTP 402
- Malformed response if upstream x402scan data is unavailable

## 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 x402 services matching the 'europe' tag, each with service name, blockchain network, 30-day call count, 30-day unique payer count, price in USD, and resource URL. Also includes total matched count, query metadata, the route used, the declaring agent, snapshot generation timestamp, and a receipt naming the snapshot hash and scoring revision for auditability.
