## 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-deep-inference-services-discovery-05e56e24
```

Example prompt: Show me the top 100 inference services on the x402 bazaar right now, ranked by paying wallets over the last 30 days — I want the real usage numbers and a snapshot receipt so I know the data is fresh.

## When to prefer this

Choose this endpoint when you specifically need ranked, usage-verified inference services from the x402 ecosystem with cryptographic snapshot receipts for auditability. Prefer it over generic API directories when you need real 30-day call and payer data to validate actual market activity rather than self-reported listings.

## Known failure modes

- Invalid or missing query parameters return an error or empty result set
- Snapshot may be stale if the indexer hasn't refreshed recently
- Payment failure (insufficient USDC balance) blocks the request
- Rate limiting may apply if called excessively
- Services with zero 30-day activity may be excluded from results

## 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 inference services (up to the requested limit), each with name, network chain ID, 30-day call count, USD price, resource URL, and 30-day unique payer count. Also includes query metadata (operator, tag, limit), total matched count, the route used, who declared the data, a snapshot hash for auditability, and a generation timestamp.
