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 on-chain x402 services, each with name, network (e.g. eip155:8453), 30-day call count, price in USD, resource URL, and 30-day unique payer count. Also includes the total matched service count, the query parameters used, the route, a snapshot hash for auditability, the scoring revision, and a generatedAt timestamp.

Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-on-chain?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a live, usage-weighted ranking of x402 services specifically tagged as on-chain or blockchain-integrated. It is preferable over generic x402 discovery endpoints when you want to filter to crypto-native services and need real 30-day activity signals (calls and unique paying wallets) rather than self-reported metadata alone. The included snapshot hash and scoring revision make it suitable for auditable or reproducible research into the x402 market.
Side effects
- No services match the on-chain tag filter — returns empty list with count 0
- Snapshot index temporarily unavailable — may return stale data or 503
- Upstream indexer lag causes recently added services to be missing from results
- Payment of $0.002 USDC not received — request rejected with 402 status
- Malformed request parameters cause 400 bad request
