x402 traffic report: requests, 402s and paid calls
Raw, public numbers from two places: the 28 x402 tools and services built and operated by the youraitools.co team (every request that reaches them), and our daily unpaid check of 369 third-party x402 listings in this directory. Nothing here is estimated.
Live data as of Oct 30, 2026, 5:59 PM ET. Request counting since Oct 23, 2026.

How to read this
- A request is any HTTP call that reaches a tool through api.youraitools.co: paid routes, free routes and remote MCP. It is not a count of people; many callers are automated agents and crawlers.
- An unpaid 402 is a client asking without payment and getting the price back. A paid call is a settled x402 payment.
- Uptime for our tools comes from a free health check every 10 minutes. Listing numbers come from one unpaid check per day, measured since Oct 27, 2026.
- Raw JSON: /stats/v1/tools and /stats/v1/listings (CC BY 4.0). Per-category measured tables are on each Best of page; prices per call are in x402 API prices.
