Honeycheck runs on your own machine — the client starts it, so there is no endpoint to ping. 55 installs a week from npm.
Before buying a token on Arc, test whether it can be sold back. Free, or 1-5c a call over x402.
Today is the operative word: we check Honeycheck every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
