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 (up to the requested limit) each with service name, network chain, 30-day call count, price in USD, resource URL, and unique payer count for the last 30 days. Also includes the total matched count, query parameters echoed back, the snapshot hash for verifiability, scoring revision, and the timestamp the snapshot was generated.
Example use cases
Finding top gateway services by usage
“What are the top 10 x402 gateway services ranked by call volume in the last 30 days? I want to see which ones have the most real traffic.”
Vetting an x402 API before integrating
“Before I build on top of an x402 service, can you look up the most popular gateway-tagged APIs and tell me which ones have the most paying wallets and highest call counts?”
Market research on x402 ecosystem activity
“I'm researching the x402 ecosystem — can you pull a ranked snapshot of all gateway services sorted by number of payers, and include the snapshot hash so I can verify the data later?”
Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, usage-weighted discovery of x402 services specifically tagged as gateways, backed by verifiable 30-day real-transaction data. Prefer it over generic x402 directory listings when you need ranking by actual economic activity (calls and paying wallets) rather than self-declared metadata. Ideal for agents doing due diligence before integrating an x402 service or for ecosystem analytics.
Side effects
- No services match the requested tag filter — returns empty services array with matched:0
- Invalid sort key or operator — may return 400 or unordered results
- Snapshot data stale if indexer is behind — generatedAt timestamp will reflect staleness
- Payment not settled (x402 $0.008 USDC) — request blocked before processing
- Rate limiting on Cloudflare Workers edge — transient 429 or 503 errors
