## 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-in-trenches-leaderboard-7fd4d0d9
```

Example prompt: Show me the top 25 x402 services in the trenches category ranked by number of paying wallets over the last 30 days, with their prices and call counts.

## When to prefer this

Choose this endpoint when you need a real-usage-backed leaderboard of x402 micro-payment services specifically in the 'trenches' category, and you want verifiable snapshot provenance (hash + scoring revision). Prefer it over generic API directories when you need actual 30-day call and payer-wallet metrics rather than self-reported stats, and when you're operating within the x402 ecosystem and need to pay per call via USDC on Base.

## Known failure modes

- Empty result set if no services currently tagged 'trenches' have 30-day activity
- Stale data if the index snapshot has not been refreshed recently
- Payment failure (402) if the $0.008 USDC micro-payment is not properly attached
- Rate limiting or worker timeout if the underlying index is under heavy load
- Malformed response if the scoring revision changes schema between versions

## 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 up to 25 (or configured limit) x402 services tagged 'trenches', each with service name, blockchain network, 30-day call count, price in USD, resource URL, and unique paying wallets in the period.
