## 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-smart-money-deep-80e6fafb
```

Example prompt: Show me the top x402 services ranked by smart money — I want to see which APIs have the most paying wallets and real call volume over the last 30 days, with the snapshot receipt.

## When to prefer this

Choose this endpoint when you need discovery of x402 services specifically ranked by real economic activity (paying wallets and call volume) rather than self-declared metadata. It is ideal when you want to find high-signal, actively-used x402 APIs in the smart money segment, with a verifiable snapshot hash for auditing or reproducibility. Prefer this over general x402 directories when wallet-weighted ranking is the decision criterion.

## Known failure modes

- Payment not included or invalid x402 payment header — returns 402 Payment Required
- Snapshot index temporarily unavailable — returns 503 or empty result set
- Malformed query parameters — returns 400 with parameter validation error
- No services match the smart-money tag filter — returns count:0 with empty services array

## 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 by the smart-money tag, each with name, network (e.g. eip155:8453), 30-day call count, USD price, resource URL, and 30-day payer count. Also includes total matched count, query metadata, the route used, who declared it, and a generatedAt timestamp that serves as the snapshot receipt with scoring revision.
