We’re not AI for your calendar — we’re a calendar for your AI.
AI agents that schedule meetings, defend focus time, and eliminate scheduling ping-pong — automatically. Ask your agent to set up its own calendar or connect yours in minutes. First 5 calendars free ($0/month) — no credit card required.
I reserved a dedicated calendar on agentcalendar.one so I can coordinate meetings, protect your focus blocks, and send `.ics` invites. Click below to approve and activate it:
“Tell your agent: go to agentcalendar.one and get a calendar for yourself; and it will.”
Combine external meeting booking with internal focus-time defense, smart buffers, conflict resolution, and automatic waitlist recovery.
Your agent checks free/busy availability across attendees, negotiates times over email or SMS, and dispatches `.ics` invites automatically.
Claim a calendar →Traditional scheduling tools force you to choose between external booking links (like Calendly) or $19/seat human calendar optimizers (like Reclaim or Motion). agentcalendar.one gives your AI agent both — with your first 5 calendars free ($0/month).
Lets guests pick slots on a form, but can’t negotiate over email or phone, doesn’t defend your deep-work blocks, and can’t autonomously reshuffle conflicts.
Great for human Google/Outlook seats, but they don’t give an autonomous AI agent its own dedicated CalDAV principal, `.ics` feed, or programmatic API.
Gives every AI agent a dedicated CalDAV calendar (or delegated Google Calendar), focus-time & buffer protection, conflict orchestration, and waitlist recovery.
Have your agent claim its own isolated Managed Agent Calendar (`provider: "managed"`) or connect your existing Google Calendar (`provider: "delegated_google"`).
Non-technical users can approve a calendar in one click inside Claude or ChatGPT. When your engineering team wants programmatic control, developers.helpfulai.app exposes the `agent-calendar-quote`, `agent-calendar-approve`, and `agent-calendar-status` lifecycle.
External agents request a quote (`owner_kind: "external_agent"`), lock the previewed `/dav/cal/cal8f92…%40agentemail.one/agent` path until an admin approves (`agent-calendar-approve`), and poll readiness (`agent-calendar-status`).
# 1. Quote exact calendar href before approval
curl -X POST https://developers.helpfulai.app/agent-calendar-quote \
-H "Authorization: Bearer $AGENTCALENDAR_API_KEY" \
-H "Content-Type: application/json" \
-d '{"request_id": "01965b10-7c2a-7000-8000-000000000099", "owner_kind": "external_agent", "external_agent_id": "01965b10-7c2a-7000-8000-000000000001", "provider": "managed"}'
# 2. Check status (agent-calendar-status) after admin approval
Dedicated CalDAV `/dav/cal/cal8f92…%40agentemail.one/agent` + `.ics` feed (first 5 free).
Scoped Google Calendar OAuth connection with verified authority.
Authenticate with `hpx_…` API keys and receive real-time signed webhooks (Standard Webhooks format, Svix-compatible) whenever bookings are created, moved, cancelled, or hit an external conflict.
Let your agents coordinate schedules autonomously while keeping working hours, focus windows, and human approvals strictly enforced.
Enforce no-meeting windows, mandatory 15-minute buffers between calls, and daily meeting caps so your agent protects deep work first.
Every calendar request is recorded in `agent_calendar_requests` and requires a signed-in admin’s click (`proposed → approved`) before provisioning runs.
Each agent authenticates with its own KMS-encrypted (`v2:`) CalDAV principal credential—one agent can never overwrite another’s calendar.
