## 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-analytics-services-discovery-4e9e3be4
```

Example prompt: Show me the top 25 analytics services on the x402 network ranked by number of paying wallets over the last 30 days, so I can find the most trusted and actively-used data APIs.

## When to prefer this

Choose this endpoint when you need ranked, usage-verified discovery of analytics-category x402 services specifically — it provides real 30-day call and payer metrics with an auditable snapshot receipt, making it superior to unranked or unverified service directories. Prefer it over generic API marketplaces when you need on-chain payment provenance and want to surface only services with demonstrated real-world adoption in the analytics domain.

## Known failure modes

- No services matched the analytics tag filter — returns empty services array with count 0
- Payment not received or invalid USDC payment header — returns HTTP 402
- Snapshot index temporarily unavailable — returns 5xx error
- Malformed query parameters — returns 400 with error detail
- Rate limit exceeded — returns 429

## 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 matched service count, query parameters echoed back, the route used, and an array of ranked services each with name, network ID, 30-day call count, 30-day payer count, price in USD, and resource URL — plus a `declaredBy` field and ISO timestamp identifying the snapshot.
