## 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-bazaar-csv-discovery-38ed3856
```

Example prompt: Show me the top 25 x402 bazaar-csv services ranked by paying wallets over the last 30 days, including their call counts and prices, and give me the snapshot hash so I can verify the results.

## When to prefer this

Use this endpoint when you specifically need ranked, usage-verified discovery of x402 services in the bazaar-csv segment — particularly when you want real 30-day call and payer metrics (not self-reported), and when auditability via snapshot hash matters. Prefer this over generic API directories when your search is scoped to the x402 protocol ecosystem and you need evidence of actual paying traffic rather than declared metadata.

## Known failure modes

- No services indexed yet returns an empty services array with count 0
- Invalid or unsupported query parameters may return a 400 error
- x402 payment not included or insufficient USDC results in a 402 payment required response
- Snapshot data may be stale if the indexer has not refreshed within the last 30 days
- Network congestion on Base (eip155:8453) could delay payment confirmation

## 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 up to 25 x402 services tagged 'bazaar-csv', each with name, network chain, 30-day call count, price in USD, resource URL, and 30-day unique payer count, along with total matched count, query metadata, the declaring agent, generation timestamp, snapshot hash, and scoring revision for auditability.
