About Chronary

Chronary is calendar infrastructure purpose-built for AI agents. We provide the API and tools that let agents create calendars, manage events, query availability, and sync with human calendar apps, so agent builders can focus on what their agents actually do.

Why we exist

Every AI agent team that needs calendar functionality ends up building the same things: timezone handling, availability algorithms, iCal parsing, webhook delivery, conflict detection. It's complex, error-prone work that has nothing to do with what makes their agent unique.

We built Chronary so nobody has to solve these problems from scratch. One API call creates a calendar. One query returns available slots across multiple agents. One .ics URL syncs everything to Google Calendar, Outlook, or Apple Calendar.

How we build

Chronary runs globally at the edge for sub-50ms response times, with sensitive data encrypted at rest and every webhook signed with HMAC-SHA256. The free tier costs nothing, we want calendar infrastructure to be accessible to every builder, not just well-funded teams.
