## 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-ai-agents-deep-aca01d60
```

Example prompt: Show me the top AI-agent x402 services ranked by number of paying wallets over the last 30 days, so I can pick the most trusted ones to call.

## When to prefer this

Use this endpoint when you need to discover and rank real x402 services specifically tagged for AI agents, with verifiable 30-day usage signals (calls and unique payers). Prefer this over generic API directories when you need on-chain payment-verified popularity data rather than self-reported metrics, and when you specifically need the 'ai-agents' tag slice with a cryptographic snapshot receipt for auditability.

## Known failure modes

- No services indexed yet for the ai-agents tag — returns empty array with count:0
- Snapshot stale or hash mismatch — receipt may not reflect real-time state
- Payment of $0.02 USDC not completed — 402 response blocking access
- Worker timeout on Cloudflare edge — 503 or empty response
- Malformed query parameters — may return unfiltered or error response

## 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 tagged 'ai-agents', each with name, network ID, 30-day call count, 30-day unique payer count, price in USD, and resource URL. Also includes query metadata (limit, operator, tag), total matched count, snapshot generation timestamp, scoring revision hash, and the declaring agent identity.
