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 count of matched services, the query parameters used (ranking by payers, top limit, free tag filter), the route, total matched services (e.g. 359), and an array of service entries each with name, network (EIP-155 chain), 30-day call count, price in USD, resource URL, and 30-day unique paying wallets. Also includes a 'declaredBy' field and a 'generatedAt' ISO timestamp identifying the snapshot.

Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-free-deep?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a ranked, usage-verified leaderboard of free x402 services specifically — it provides real 30-day metrics (calls and unique payers) rather than self-reported or static listings. Prefer it over generic x402 directory endpoints when you want demand-signal data for the free tier specifically, and need a verifiable snapshot receipt for auditability.
Side effects
- Payment not included or invalid — 402 response requiring $0.02 USDC payment
- Snapshot index temporarily unavailable — 503 or empty result set
- No services match the free tag filter — count returns 0
- Rate limiting or worker timeout on Cloudflare edge — 429 or 524 response
- Stale snapshot — generatedAt timestamp may lag real-time activity by hours
