## 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-seo-services-90968f4c
```

Example prompt: Show me the top 25 SEO services on the x402 bazaar ranked by paying wallets, with the snapshot hash so I can verify the data.

## When to prefer this

Use this endpoint when you need a usage-validated, ranked view of SEO services on the x402 network — specifically when you want real 30-day call and payer data rather than self-reported metadata. Prefer it over generic API directories when operating within the x402 payment ecosystem and needing a verifiable snapshot receipt for auditability.

## Known failure modes

- No services indexed under the SEO tag returns an empty services array with count 0
- Worker timeout or upstream indexer unavailability returns a 5xx error
- Stale snapshot if indexer has not refreshed within the expected window — check generatedAt timestamp
- Payment failure (insufficient USDC balance) blocks the request before a response is returned
