402index runs on your own machine — the client starts it, so there is no endpoint to ping. 102 installs a week from npm. Last commit 28 Oct 2026.
Search 15,000+ paid API endpoints across the L402, x402, and MPP protocols on 402index.io
Today is the operative word: we check 402index every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
