## 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-random-tag-discovery-f50bc18d
```

Example prompt: Show me the top x402 services in the random category ranked by number of paying wallets over the last 30 days, with their prices and call counts.

## When to prefer this

Choose this endpoint when you need a real-usage-backed ranked list of x402 services in the 'random' category, specifically when you want scoring based on actual 30-day call and payer data rather than self-reported metadata. Prefer it over generic API directories when you need a verifiable snapshot hash for audit trails or when operating within the x402 micropayment ecosystem and need to identify high-trust, actively-used services.

## Known failure modes

- No services indexed under the 'random' tag — returns empty services array
- Payment of $0.004 USDC not provided or rejected — HTTP 402 response blocking access
- Snapshot data stale or scoring revision unavailable — may return outdated rankings
- Worker cold-start latency on Cloudflare edge — occasional slow first response
- Malformed response if the bazaar index is being rebuilt — partial or empty result set

## How this service works

Highest-demand x402 services tagged 'random': ranked by 30-day unique paying wallets, with calls, price, network and calls-per-payer for each. 31 providers and 268 paying wallets measured in this tag.

## Output

A JSON object containing: count of returned services, the query parameters used (tag, operator, limit), the route called, total matched services, and an array of service objects each with name, network chain ID, 30-day calls, price in USD, resource URL, and 30-day payer count. Also includes a declaredBy field, generation timestamp, and a receipt identifying the snapshot hash and scoring revision for auditability.
