## 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-3b8b3ffc
```

Example prompt: Pull the current ranked list of x402 services from the Bazaar — I want to see which APIs are leading by real 30-day call counts and paying-wallet activity, along with the snapshot hash so I can verify the data.

## When to prefer this

Choose this endpoint when you need a ranked, trustworthy view of the live x402 service ecosystem backed by real on-chain payment signals rather than self-reported metrics. It is particularly valuable when you want verifiable data (snapshot hash + scoring revision) for auditing or when building dashboards that track x402 market activity. Prefer it over generic API directories when the x402 payment protocol is your specific domain of interest.

## Known failure modes

- Payment not received — $1.25 USDC required per call via x402 protocol
- Snapshot data temporarily unavailable if indexing pipeline is delayed
- Malformed properties filter parameter returns empty or unexpected results
- Rate limiting if wallet sends too many requests in a short window
- Stale data if the 30-day rolling window has not yet refreshed
