## 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-fun-category-3e7e48dc
```

Example prompt: Show me the top 25 fun services on the x402 bazaar ranked by number of paying wallets, so I can see which ones are actually being used.

## When to prefer this

Use this endpoint when you specifically want to discover or rank x402-protocol services in the 'fun' category, sorted by real economic activity (paying wallets and call volume) rather than self-reported popularity. Prefer this over generic API directories when you need verifiable, on-chain-backed usage signals and a tamper-evident snapshot receipt for auditability. Not suitable for non-fun categories or for services outside the x402 ecosystem.

## Known failure modes

- No services indexed for the 'fun' tag — returns empty services array
- Snapshot data stale if market indexer lags — generatedAt timestamp reveals freshness
- Payment of $0.008 USDC required per call; missing or invalid x402 payment header results in 402 response
- Malformed request parameters may return an error or default behavior
- Worker cold start may add minor latency on first request

## 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 x402 services tagged 'fun', each with name, network chain ID, 30-day call count, price in USD, resource URL, and 30-day unique payer count. Also includes query metadata (operator, limit, tag), total matched service count, the declaring agent, generation timestamp, and a snapshot hash for audit purposes.
