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 (by default) filtered to the 'history' tag, sorted by 30-day payer count descending. Each entry includes the service name, blockchain network, 30-day call count, price in USD, resource URL, and 30-day unique payer count. The response also includes the total number of matched services, the query parameters used, the snapshot generation timestamp, and a receipt identifying the snapshot hash and scoring revision for auditability.

Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-history?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a ranked, verifiable snapshot of the x402 service market specifically ordered by unique paying wallet activity (payer count), and you want an auditable receipt with snapshot hash. Prefer this over general API directories when you need real 30-day usage signals from actual paying agents rather than self-reported or static listings. It is the right choice for agent-economy discovery, not for general web API search or non-x402 protocol listings.
Side effects
- Stale index data if the snapshot has not been refreshed recently
- Empty or low result set if few history-tagged services exist in the index
- Payment failure (402) if the 0.032 USDC x402 payment is not attached or rejected
- Rate limiting or worker timeout on the Cloudflare Workers edge runtime
- Partial data: payer counts only available for x402 and Tempo MPP sources; other protocols may show nulls
