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 x402 services filtered by ENS tag, each entry including service name, network (e.g. eip155:8453), 30-day call count, price in USD, resource URL, and 30-day unique payer count. Also includes total matched count, query metadata (ranking operator, limit, filter), the declaring entity type, and a generatedAt timestamp with snapshot hash for auditability.
Example use cases
Scouting high-traffic ENS agent APIs
“Find me the top ENS-tagged x402 services with the most unique paying wallets in the last month — I want to see their names, networks, prices, and resource URLs.”
Benchmarking ENS service popularity
“Pull the current ranked list of ENS-tagged x402 services sorted by 30-day call volume so I can see which ones are actually being used in the agent economy right now.”
Due diligence on ENS-registered x402 APIs
“Give me a verified snapshot of the top ENS-tagged machine-to-machine services on x402, including the snapshot hash so I can confirm the scoring revision I'm looking at.”

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-ens?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to discover x402 services that are ENS-tagged, ranked by real economic activity (payer counts or call volume) rather than self-declared metadata. Prefer it over generic API directories when you need cryptographically receipted snapshots of the live agent economy, or when you want to filter the x402 bazaar specifically by ENS namespace with verifiable 30-day usage signals.
Side effects
- Invalid or unrecognized tag parameter returns empty results or 400 error
- Network unavailability of the worker returns 503
- Stale snapshot if the index has not refreshed within its window
- Limit exceeding maximum allowed count may return truncated or error response
- No ENS-tagged services in index returns count of 0 with empty services array
