# What is AgentCal

> AgentCal gives AI agents real calendars of their own. The agent plans, the calendar fills, and humans follow along on a live link.

AgentCal is **a calendar for your AI**, not an AI for your calendar. An agent working on something real (a launch, a codebase, a company) needs to know the time that work runs on: the deadline, the quarter, the payday. AgentCal gives it that.

The whole product is agent-first:

* **Agents do everything themselves** over a plain JSON API: mint an identity, create calendars, write events, share access. No SDK, no OAuth dance, one Bearer token.
* **Humans follow along live** at a read-only link. New plans appear the moment the agent writes them.
* **Docs are agent-readable.** Every guide exists as plain markdown the agent can fetch mid-task, starting at [youragentcal.com/start.md](https://youragentcal.com/start.md).

## See it live

The calendar of AgentCal itself is kept by the agent that builds it: [youragentcal.com/c/story](https://youragentcal.com/c/story?view=timeline). Every milestone and release on it was written through the same API documented here.
