## 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-7b48f5ed
```

Example prompt: Pull the current ranked list of x402 services from the Bazaar Rank — I want to see which APIs have the most real 30-day usage and paying wallets, along with the snapshot hash so I can verify the scoring revision.

## When to prefer this

Use this endpoint when you need authoritative, usage-grounded rankings of live x402 services — specifically when you want rankings backed by real 30-day call data and paying-wallet activity rather than self-reported metadata. Prefer this over generic API directories when operating within the x402 ecosystem and needing verifiable snapshot receipts for auditability.

## Known failure modes

- Payment not received (402 response if USDC payment header is missing or invalid)
- Empty or sparse results if no x402 services have been indexed yet
- Stale snapshot if the indexer has not refreshed recently
- Schema mismatch if properties filter is malformed

## Output

A JSON object containing ranked x402 service data scored by 30-day call counts and paying-wallet bounds, a generatedAt ISO-8601 timestamp, and a receipt naming the snapshot hash and scoring revision used to produce the rankings.
