## 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-trading-deep-39a90ede
```

Example prompt: Show me the top x402 trading services ranked by paying wallets over the last 30 days — I want to know which ones have real usage, their call counts, prices, and the snapshot hash so I can verify the data.

## When to prefer this

Use this endpoint when you need to discover x402 protocol services specifically in the trading/DeFi category ranked by real economic activity (paying wallets and call volume) rather than self-reported metadata. Prefer this over generic API directories when you need cryptographically verifiable snapshot receipts and on-chain usage signals, or when building an agent that needs to programmatically select a trading service based on proven market adoption.

## Known failure modes

- No services match the trading tag — returns empty services array with count 0
- Snapshot index temporarily unavailable — may return stale or error response
- Rate limiting or payment failure — 402 response if USDC payment not processed
- Malformed response if scoring revision is mid-update during request

## 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 the route used, a query descriptor (ranking by payers, top 100, tag=trading), total matched service count, and an array of ranked services each with name, network (EIP-155 chain), 30-day call count, USD price, resource URL, and 30-day unique payer count. Also includes a 'declaredBy' field and a 'generatedAt' ISO timestamp plus snapshot hash for auditability.
