Fastx402 runs on your own machine — the client starts it, so there is no endpoint to ping. 634 installs a week from npm. Last commit 17 Oct 2026.
60+ pay-per-call tools for agents (data, dates, QR, crypto, web), paid in USDC via x402.
Today is the operative word: we check Fastx402 every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
