## 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-in-web-deep-discovery-40baf365
```

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

## When to prefer this

Choose this endpoint when you need ranked, usage-verified discovery of x402 services specifically in the web category, backed by real 30-day on-chain activity (calls and paying wallets) rather than self-reported metadata. Prefer it over generic API directories when you want auditability via snapshot hash and scoring revision, or when you need to find which x402 services are actually being paid for rather than just listed.

## Known failure modes

- No services indexed yet — returns empty services array with count 0
- Upstream indexer unavailable — may return 5xx from Cloudflare Worker
- Payment not included or insufficient — 402 response requiring USDC payment
- Malformed query parameters — may return 400 with error detail
- Snapshot data stale if indexer hasn't refreshed in 30-day window

## How this service works

An open index of the machine-to-machine (agent) economy. x402 routes: 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. /economy routes, for Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry): each protocol's published figures (agent or server counts, transactions or payment events; payers and USD volume only where the source publishes them: payers for x402 and Tempo MPP, USD volume for x402 and Virtuals ACP), each with its unit, window and source; units differ, so totals are not summed. L402 and per-service MPP listings are not covered.

## Output

A JSON object containing a ranked array of x402 services filtered to the 'web' tag, each entry including service name, network chain ID, 30-day call count, price in USD, resource URL, and 30-day unique payer count. The response also includes total matched count, the query parameters used, the route, generation timestamp, and a receipt identifying the snapshot hash and scoring revision for auditability.
