## 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-trading-e8e936a5
```

Example prompt: Show me the top 25 trading services on the x402 Bazaar, ranked by the most paying wallets over the last 30 days, so I can find which APIs are actually being used.

## When to prefer this

Use this endpoint when you need authoritative, usage-verified rankings of x402 trading services specifically — it provides real 30-day payment and call-volume data rather than self-reported or static listings. Prefer it over generic API directories when you need to identify which trading services have proven traction among paying wallets on the x402 network.

## Known failure modes

- No services indexed under 'trading' tag returns count:0 with empty services array
- Network timeout from Cloudflare Worker returns 5xx error
- Stale snapshot if indexer hasn't refreshed recently, indicated by older generatedAt timestamp
- Payment failure (insufficient USDC balance) blocks the request before any data is returned
- Malformed response if snapshot hash or scoring revision is unavailable
