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 confirming the request succeeded (ok: true), a timestamp, a blockchain transaction hash on Base (network eip155:8453), the payer wallet address, the route called, a Basescan explorer link for the payment, the price paid in USD ($0.001), and the facilitator used (coinbase-cdp). The ranked service data reflects 30-day call volume and paying-wallet bounds with a receipt identifying the snapshot hash and scoring revision.

Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/x402-ping?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need ranked, usage-verified discovery of x402 services backed by on-chain payment evidence rather than self-reported metadata. It is uniquely suited for agents that need to identify high-signal, actively-used x402 APIs with auditable snapshot hashes, as opposed to static directories or unverified listings.
Side effects
- Payment failure if wallet has insufficient USDC balance — returns 402
- Stale snapshot if ranking index has not refreshed recently
- Empty result set if no x402 services are currently indexed
- Network errors on Base blockchain preventing payment settlement
- Invalid or missing x402 payment header returns 402 without data
