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 N x402 services (defaulting to 25), each with name, network chain ID, 30-day call count, 30-day unique payer wallet count, USD price, and resource URL. The response also includes total matched count, the query parameters used, the snapshot hash for verifiability, scoring revision, and a generation timestamp.

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-agent-tool?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-usage-validated discovery of x402 agent-tool services — not just directory listings, but rankings grounded in actual 30-day call counts and unique paying wallets. It is especially useful when you want to identify which services have genuine market traction before integrating them into an agent workflow, or when you need a verifiable, timestamped snapshot of the x402 service market for auditing or reproducibility.
Side effects
- No services matched the agent-tool tag — returns empty services array with count 0
- Snapshot index temporarily unavailable — may return stale or error response
- Rate limit or payment failure — 402 response requiring valid USDC payment of $0.008
- Malformed query parameters — may return 400 or unexpected empty results
- Network indexing lag — very recently listed services may not appear in 30-day window
