## 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-discovery-3285d69c
```

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

## When to prefer this

Choose this endpoint when you need ranked, traction-validated discovery of security-specific x402 services backed by real on-chain payment data rather than self-reported metadata. Prefer it over generic x402 service listings when you specifically want the 'sec' tag segment and need a scoring receipt for auditability or reproducibility.

## Known failure modes

- No services indexed under the 'sec' tag — returns empty results array with count 0
- Snapshot hash unavailable or scoring engine offline — may return stale or error response
- Rate limiting or payment validation failure — 402 response requiring USDC payment
- Malformed response if the bazaar index is mid-refresh — partial or inconsistent data
- Network timeout on Cloudflare Worker — 504 gateway timeout

## How this service works

Highest-demand x402 services tagged 'sec': ranked by 30-day unique paying wallets, with calls, price, network and calls-per-payer for each. 172 providers and 332 paying wallets measured in this tag.

## Output

A JSON object containing the total count of matched services, the query parameters used (tag, operator, limit), the route, the number of matched services, and an array of ranked service entries each with name, network chain ID, 30-day call count, price in USD, resource URL, and 30-day paying-wallet count, plus metadata fields for who declared it and the snapshot generation timestamp.
