UnCorreoTemporal runs on your own machine — the client starts it, so there is no endpoint to ping. 91 installs a week from pypi. Last commit 19 Apr 2026.
Temporary email for AI agents: create inboxes, wait for emails, extract OTPs, verify signups.
Today is the operative word: we check UnCorreoTemporal every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
