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 x402 services filtered by the 'buyers' tag, sorted by payer activity. Each entry includes the service name, network (e.g. eip155:8453), 30-day call count, price in USD, resource URL, and 30-day unique payer count. The response also includes total matched count, query metadata, a snapshot hash for auditability, the scoring revision, and a generatedAt timestamp.

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-buyers?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need an objective, usage-backed ranking of x402 services specifically by buyer (paying wallet) activity. It is distinct from call-volume-only rankings because it surfaces services with real economic demand — multiple unique payers — rather than just high call frequency from a single source. Prefer it over generic API directories when you need cryptographically receipted, snapshot-auditable results tied to the live x402 payment network on Base (eip155:8453).
Side effects
- No services indexed yet — returns empty array with count 0
- Snapshot stale — generatedAt timestamp may be hours old if indexing is delayed
- Network errors from Cloudflare Worker cold start — retry after brief pause
- Invalid query parameters result in malformed or empty response
- Payment failure (402) if USDC payment header is missing or insufficient
