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 'mcp', each with name, blockchain network, 30-day call count, USD price, resource URL, and unique paying wallet count; plus aggregate metadata including total matched services, query parameters used, snapshot hash, scoring revision, and generation timestamp.
Example use cases

“I'm building an agent that needs to call x402 MCP services — show me the top 25 ranked by paying wallets over the last 30 days so I can pick the most battle-tested ones.”
Benchmarking x402 market activity
“Pull the current x402 Bazaar ranking for mcp-tagged services by call volume and tell me the snapshot hash — I want to track how the leaderboard shifts week over week.”

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-mcp?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need objective, usage-verified rankings of x402 MCP services backed by on-chain payment data rather than self-reported metadata. Prefer it over generic API directories when you specifically want services that have demonstrated real paying traffic in the last 30 days on the x402 protocol, and need an auditable snapshot hash to verify data provenance.
