payware runs on your own machine — the client starts it, so there is no endpoint to ping. 85 installs a week from npm. Last commit 17 Sep 2026.
payware A2A payments API for merchants, ISVs and payment institutions
Today is the operative word: we check payware every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
