## 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-security-services-d31ef842
```

Example prompt: Show me the top 25 security services on the x402 bazaar ranked by paying wallets over the last 30 days, and tell me which snapshot and scoring version the results come from.

## When to prefer this

Choose this endpoint when you need ranked, usage-verified discovery of security-focused x402 services specifically — it provides real 30-day transaction and payer data rather than static listings, and includes an auditable snapshot hash plus scoring revision. Prefer it over generic API directories when you need trustworthiness signals (actual paying wallets) rather than self-reported metadata. Best when building agent toolchains that need to dynamically select the best active security APIs on the x402 network.

## Known failure modes

- No services indexed under the security tag — returns empty services array
- Snapshot data stale if indexer has not run recently — generatedAt timestamp may be old
- Rate limiting or payment failure (x402 protocol) if USDC payment of $0.008 is not included or rejected
- Invalid route path returns 404 or empty result
- Network connectivity issues to Cloudflare Workers endpoint
