Calendar infrastructure
The only calendar API built for AI agents.
Connect every calendar. One unified API. Your agent handles the rest.
Launching soon — almost there
No spam. One email when we launch.
One API. Every calendar.
Query events, check availability, detect conflicts, book slots — across Google, Microsoft, Apple, CalDAV, and iCal feeds.
