Calendar infrastructure
for AI agents

Your agents need to manage schedules, not fight with calendar APIs. Limehouse gives them a calendar server that speaks their language — simple REST, real-time webhooks, and auth that just works.

create_calendar.py
import limehouse# Create a calendar for your agentclient = limehouse.Client("lh_sk_...")cal = client.calendars.create(name="Team Standup")# Subscribe to event changes via webhookclient.webhooks.create(    calendar_id=cal.id,    url="https://myapp.dev/hooks/calendar",    events=["event.created", "event.updated", "event.cancelled"])# Create an event — attendees get scoped tokens automaticallyclient.events.create(    calendar_id=cal.id,    title="Sprint Planning",    starts_at="2026-02-17T10:00:00Z",    duration_minutes=30,)

Built for agents, not humans clicking buttons

Every calendar API was designed for human users with OAuth flows and UI widgets. Limehouse is designed from the ground up for programmatic access.

Real-time webhooks

Subscribe to event.created, event.updated, event.cancelled, and more. Your agent reacts the moment a schedule changes — no polling.

API-first design

Create calendars, manage events, invite attendees, handle conflicts — all through clean, predictable REST endpoints. No UI required.

Scoped auth tokens

Issue fine-grained tokens per agent, per calendar, or per event. No OAuth dance — just API keys with the right permissions.

Timezone-aware

Every event stores an IANA timezone. Queries return results in the timezone you ask for. No more UTC-only headaches.

Conflict detection

Automatically detect double-bookings and overlapping events. Let your agent resolve conflicts or flag them for humans.

Multi-tenant

One Limehouse account, unlimited calendars. Isolate calendars per customer, per team, or per agent — with full audit logs.

Three lines to your first calendar

No config files, no OAuth setup, no provisioning. Get an API key and start creating calendars in seconds.

01

Get your API key

Sign up and grab a key from the dashboard. That's your only credential — no client secrets, no redirect URIs.

02

Create a calendar

One POST request gives your agent its own calendar. Scope it to a user, a team, or an entire org.

03

Subscribe & react

Register a webhook URL and pick your events. Your agent gets notified instantly when anything changes.

Webhooks that tell you exactly what changed

Every webhook payload includes the full event diff — previous values, new values, and who made the change. Your agent always has the context it needs to act.

  • Signed payloads with HMAC-SHA256
  • Automatic retries with exponential backoff
  • Delivery logs in the dashboard
  • Filter by event type, calendar, or metadata

Auth that agents understand

Forget OAuth consent screens and refresh token juggling. Limehouse uses scoped API tokens that you can issue, rotate, and revoke programmatically.

  • Root, calendar-scoped, or event-scoped tokens
  • Token creation via API — no dashboard required
  • Built-in expiration and automatic rotation
  • Audit log for every authenticated action
