Why AI agents fail at scheduling (and how to fix it)

Current calendar APIs are designed for human UIs, which makes agent scheduling error-prone.

Agents must perform many sequential, stateful steps to find mutual availability using raw calendar APIs.

MeetSync offers an agent-focused API with API-key auth, explicit timezone offsets, UUIDs, and ranked slot outputs.

Using MeetSync, an agent can register participants, get ranked availability, and create a booking with five tool calls.
