## 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-json-discovery-6c27d6a5
```

Example prompt: Show me the top x402 services tagged as JSON, ranked by 30-day paying wallets, so I can find the most actively used micropayment APIs right now.

## When to prefer this

Choose this endpoint when you need to discover and rank live x402 micropayment services specifically tagged as JSON APIs, using real 30-day usage signals (call volume and unique payer wallets) rather than static listings. Prefer it over generic API directories when you need verifiable, pay-gated market data with an auditable snapshot hash and scoring revision — especially when building agent workflows that need to programmatically select the best x402 service to call next.

## Known failure modes

- No services indexed for the json tag — returns empty array with count 0
- Snapshot index stale or unavailable — may return outdated data without warning
- Rate limit or payment failure — endpoint requires $0.04 USDC per call via x402 protocol
- Malformed query parameters — returns error or empty result set
- Worker timeout on large index scans — partial or truncated 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 x402 services filtered by the 'json' tag, each entry including the service name, blockchain network, 30-day call count, USD price, resource URL, and 30-day unique paying wallet count. Also includes total matched count, the query parameters used, a snapshot hash for auditability, and a generation timestamp.
