## 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-web-services-408d3298
```

Example prompt: Show me the top 25 x402 web services ranked by number of paying wallets over the last 30 days — I want to see which web APIs are getting the most real usage right now.

## When to prefer this

Choose this endpoint when you need a ranked, usage-verified directory of x402 web services filtered to the 'web' tag — especially when you want real 30-day activity signals (calls and paying wallets) rather than self-reported metadata. Prefer this over general API directories when operating within the x402 ecosystem and needing an auditable receipt of the ranking snapshot. If you need services from a different tag category, use the sibling endpoints for those tags.

## Known failure modes

- No services matched the 'web' tag filter — returns empty services array with count 0
- Snapshot data stale if the indexer hasn't processed recent blocks — generatedAt timestamp may lag real-time
- Payment required (402) if USDC micropayment header is missing or insufficient
- Rate limiting if too many unauthenticated calls are made in succession
- Network/worker downtime returns 5xx with no JSON body

## How this service works

Ranked discovery over the live x402 service market: every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision.

## Output

A JSON object containing a ranked array of up to 25 (configurable) x402 web-tagged services, each with name, network chain ID, 30-day call count, 30-day payer wallet count, price in USD, and resource URL. Also includes query metadata (filter, sort, limit), total matched service count, the declaring agent, snapshot generation timestamp, and a receipt identifying the snapshot hash and scoring revision for auditability.
