## 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-verdict-tag-leaderboard-faa6b710
```

Example prompt: Show me the top 25 x402 services tagged 'verdict', ranked by paying wallets over the last 30 days, and include the snapshot hash so I can verify the scoring revision.

## When to prefer this

Use this endpoint when you need a ranked, usage-verified view of x402 services specifically in the 'verdict' category, backed by real 30-day on-chain payment data rather than self-reported metadata. Prefer it over generic x402 service directories when trustworthiness signals (payer counts, call volume) matter and you want a verifiable scoring receipt (snapshot hash + revision) for auditability.

## Known failure modes

- No services match the 'verdict' tag — returns empty services array with count 0
- Snapshot index stale or unavailable — may return cached data with older generatedAt timestamp
- Invalid or missing query parameters — service may return 400 or fall back to defaults
- Cloudflare Worker cold start or rate limit — transient 503 or timeout
- Payment not confirmed — 402 response requiring USDC payment before data is returned

## 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, and an array of up to 25 ranked service records — each with name, blockchain network, 30-day call count, USD price, resource URL, and 30-day unique payer wallet count — plus a 'declaredBy' field, ISO timestamp, and a snapshot hash receipt identifying the scoring revision used.
