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: total matched service count, the query parameters used, a list of up to 25 ranked services each with name, network chain ID, 30-day call count, USD price, resource URL, and 30-day unique payer count, plus metadata fields for who declared the data, the snapshot generation timestamp, and a scoring revision receipt.
Example use cases
Leaderboard of deterministic x402 APIs
“Pull the top 25 deterministic services from the x402 bazaar ranked by paying wallets this month — I want to see which ones have genuine traction before I integrate them.”
Vetting an x402 service before integration
“Check the x402 bazaar rank for deterministic services and tell me the call volume and unique payer count for any forecast or oracle APIs — I want to pick the one with the strongest real usage.”
Market research on x402 deterministic APIs
“Give me a snapshot of the deterministic x402 service market: how many services are indexed, what do the top ones cost, and who leads by 30-day calls?”

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-deterministic?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need ranked, usage-validated discovery of deterministic x402 services specifically — it combines real 30-day call and payer data with a cryptographic snapshot receipt, making it more trustworthy than static registries. Prefer it over generic x402 service lists when you want to identify which deterministic APIs have genuine market adoption rather than just being listed.
Side effects
- No services match the deterministic tag filter — returns empty services array with matched:0
- Snapshot data is stale if the bazaar index hasn't been refreshed recently — generatedAt timestamp reveals age
- Invalid or missing query parameters may return a 400 error
- Service may return partial data if the x402scan index is incomplete
- Payment of 0.032 USDC required per call — unpaid requests return HTTP 402
