## 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-base-network-services-0340a9aa
```

Example prompt: Show me the top 25 most-used x402 services on the Base network right now, ranked by paying wallets over the last 30 days.

## When to prefer this

Choose this endpoint when you need ranked, real-usage-backed discovery of x402 micropayment services specifically on the Base (eip155:8453) network. It is preferable to generic API directories because rankings are derived from actual 30-day call and payer data rather than self-reported metadata, and each response includes a verifiable snapshot receipt. Best used when you want to identify which services have genuine adoption, compare market activity, or build integrations on top of proven Base network APIs.

## Known failure modes

- No services matched the 'base' tag filter — returns empty services array with matched:0
- Snapshot index stale or unavailable — may return cached or partial data without fresh 30-day metrics
- Rate limiting or payment failure — 402 response if the $0.002 USDC micropayment is not processed
- Worker cold-start latency on Cloudflare edge — occasional slow first response
- Malformed response if scoring revision changes and client expects old schema

## 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 the count of returned services (up to the limit), the query parameters used, the total matched service count, and an array of ranked service records each with name, network ID, 30-day call count, price in USD, resource URL, and 30-day unique payer count. Also includes a 'declaredBy' field, snapshot generation timestamp, and a receipt naming the snapshot hash and scoring revision for auditability.
