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 'responses-api', each with name, network, 30-day call count, USD price, resource URL, and 30-day unique payer count. Also includes the total matched service count, the query parameters used, the route, who declared the data, and a generatedAt timestamp serving as a snapshot receipt with scoring revision provenance.

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-responses-api?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need ranked discovery of x402 services in the responses-api category, filtered and scored by real on-chain payment activity (calls and unique payers) over the last 30 days. Prefer this over generic API directories when you need trust signals derived from actual paying wallets rather than self-reported metadata, and when you need a cryptographically anchored snapshot receipt for auditability.
Side effects
- No services found matching the 'responses-api' tag — returns empty results array with matched:0
- Stale snapshot if the indexer hasn't refreshed recently — generatedAt timestamp may lag real-time
- Payment failure if USDC balance is insufficient for the $0.032 per-call fee
- Rate limiting or worker timeout if the Cloudflare Worker is under heavy load
- Malformed response if the upstream index is being rebuilt or rotated
