## 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-weather-services-discovery-bb9d1d76
```

Example prompt: Show me the top 25 weather services on the x402 bazaar ranked by number of paying wallets over the last 30 days, so I can pick the most trusted one to call.

## When to prefer this

Use this endpoint when you need a pre-filtered, usage-ranked view of weather services specifically available on the x402 micropayment network. Prefer it over generic API directories when you want real 30-day activity signals (calls and paying wallets) rather than self-reported metrics, and when you need verifiable receipts for auditability of the discovery snapshot.

## Known failure modes

- No weather-tagged services indexed — returns empty services array with matched:0
- Snapshot stale or hash mismatch — receipt may indicate outdated scoring revision
- Worker cold-start latency — occasional slow first response on Cloudflare Workers
- Invalid query parameters — may return 400 or empty result set
- x402 payment not fulfilled — 402 response requiring USDC payment before data is returned

## How this service works

Highest-demand x402 services tagged 'weather': ranked by 30-day unique paying wallets, with calls, price, network and calls-per-payer for each. 133 providers and 232 paying wallets measured in this tag.

## Output

A JSON object containing a ranked array of weather-tagged x402 services, each with its name, blockchain network, 30-day call count, price in USD, resource URL, and 30-day payer count. Also includes the total matched service count, the query parameters used, the snapshot generation timestamp, and a receipt identifying the snapshot hash and scoring revision for auditability.
