## 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-funding-rate-route-cb0a254e
```

Example prompt: Show me the top 25 funding-rate services on the x402 bazaar ranked by paying wallets over the last 30 days, and include the snapshot receipt so I can verify the scoring.

## When to prefer this

Choose this endpoint when you need ranked, usage-verified discovery of funding-rate data services within the x402 payment ecosystem specifically — where real 30-day call counts and paying-wallet bounds are required for trust signals, rather than self-reported metadata. Prefer it over generic API directories when you need on-chain payment provenance and a verifiable snapshot receipt.

## Known failure modes

- No services indexed under 'funding-rate' tag returns an empty services array
- Stale snapshot if the worker cache hasn't refreshed within the 30-day window
- HTTP 402 if the $0.032 USDC payment is not attached or fails
- Worker cold-start latency on first request
- Snapshot hash mismatch if the index was rebuilt mid-request
