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 the ranked list of FX-tagged x402 services (up to the requested limit), each with name, network, 30-day call count, 30-day unique payer count, price in USD, and resource URL. Also includes total matched count, the query parameters echoed back, a snapshot hash for auditability, the scoring revision, and a generatedAt timestamp.
Example use cases
FX API leaderboard for agent routing
“I need to pick the most reliable x402 currency exchange API for my agent — can you pull the top-ranked FX services by real 30-day call volume from the bazaar and show me their prices and resource URLs?”
Vetting x402 FX services by payer diversity
“Which x402 FX services have the most unique paying wallets in the last month? I want to avoid services that are inflated by a single heavy user.”
Market snapshot for x402 FX ecosystem
“Give me a snapshot of the x402 FX service market right now — how many services are indexed, what's the top-ranked one by calls, and what snapshot hash is this report based on?”
Technical details
Endpoint
GEThttps://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/in-fx?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a usage-grounded ranking of x402 FX services specifically — it combines real 30-day call and payer data rather than static listings, making it ideal for agent routing decisions, ecosystem monitoring, or due diligence on which FX micropayment APIs are genuinely active. Prefer it over generic API directories when you need on-chain-verified activity signals scoped to the fx tag.
Side effects
- No FX-tagged services indexed yet — returns empty services array with matched:0
- Snapshot data stale if indexer hasn't run recently — generatedAt timestamp may lag real-time
- Rate limit or payment failure returns 402 if USDC payment not attached
- Worker cold-start latency on first call after idle period
- Malformed query parameters may return 400 or empty results
