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 list of up to 25 x402 services tagged 'classify', ordered by 30-day payer count. Each entry includes service name, network (e.g. eip155:8453 for Base), 30-day call count, price in USD, resource URL, and payer count. The envelope includes the total matched count, the query parameters used, the route, a declarant field, and a generatedAt timestamp anchoring the snapshot.

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-classify?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to discover and rank x402 services tagged 'classify' by real paying-wallet activity rather than self-reported metrics. It is ideal when an agent needs to programmatically select the most credible classification API based on actual 30-day payment data from the live agent economy, rather than relying on documentation claims or star ratings. Prefer it over general API directories when operating within the x402/Base ecosystem and when payer-count legitimacy signals matter.
Side effects
- No services match the 'classify' tag — returns empty services array with count:0
- Snapshot data stale if underlying x402 indexer has not refreshed — generatedAt timestamp indicates age
- Payment of $0.048 USDC required per call; missing or invalid x402 payment header returns 402
- Worker cold-start latency may cause occasional timeouts on Cloudflare edge
- If fewer than 25 classify-tagged services exist, count will be less than the requested limit
