cancel_booking_as_invitee
Cancel a booking (invitee)
Cancels a booking by its id and token. The event is removed from the host's calendar. Paid bookings cancelled before `refundableUntil` are refunded in full. Later cancellations get no refund. The event type sets the rules, which get_booking shows: no changes after `changeableUntil` (409 change_too_late), no cancelling when `canCancel` is false (409 cancel_not_allowed, reschedule instead), and a `reason` when `cancelReasonRequired` is true (422 reason_required).

check_series
Check a repeating series before booking it
For event types with `repeatMax` (from get_public_profile): lists each meeting of a series that starts at `start` (one of the slots) and repeats `every` 1, 2 or 4 weeks at the same local time, and whether each is free. Book it with create_booking and `repeat` when `bookable` is true. A series is booked whole or not at all, and round robin gives every meeting to the same host.

create_booking
Book a meeting
Books `start`, which must be one of the `slots` from get_available_slots. Free events are confirmed at once, unless the event type has `requiresApproval`: then it's a request (status=pending_approval) that holds the time until a host approves or declines it, and the invitee hears either way by email. Tell the human it isn't confirmed yet. Paid events return status=pending_payment and a `paymentUrl`. Give it to the human to pay before `holdExpiresAt`, or the slot is released. Once confirmed, the event is added to the host's calendar if they connected one, and the invitee gets its invitation. Keep `manageUrl` and `token`: they are the only way to view, reschedule or cancel later. 409 slot_unavailable means the time was just taken: fetch slots again.

get_available_slots
Find open times
Returns the start times that can be booked, with the hosts' calendars, buffers and limits already applied. Pass `date` (YYYY-MM-DD in `timezone`) or `from` and `to` (ISO, at most 62 days apart). With neither, it covers the next 7 days. `days` groups the slots by date in `timezone` (default UTC). For new times for an existing booking, also pass its `bookingId` and `token`. Next: call create_booking (or reschedule_booking_as_invitee) with one of the `slots` values as `start`.

get_booking
View a booking (invitee)
Returns a booking by its id and token (from create_booking or its manageUrl), with `changeableUntil`, `refundableUntil`, `canCancel` and `cancelReasonRequired`. For a series, `series` lists every meeting with its own manageUrl.

get_public_profile
List a person's or team's event types
Takes a handle, the first path segment of a booking link (https://host/acme/demo → "acme"). Returns the person or team and their bookable event types, with duration, price and hosts. A handle from before a rename also works. Next: call get_available_slots with one of the event type slugs.

join_waitlist
Join the private beta waitlist
Requests access to host on Tempi (create event types, share a booking page). Not needed to book meetings, since booking pages are public. Returns the status: pending, approved (sign in to the Tempi web app), rejected, or open (no waitlist, sign in directly). Joining again with the same email returns the current status.
Input schema
{'type': 'object', 'required': ['email'], 'properties': {'ref': {'type': 'string', 'pattern': '^[a-z0-9_-]{1,32}$', 'description': 'a short source tag of lowercase letters, digits, - or _, like "embed"'}, 'name': {'type': 'string', 'title': 'maxLength(100)', 'maxLength': 100, 'minLength': 0, 'description': 'a string at most 100 character(s) long'}, 'note': {'type': 'string', 'title': 'maxLength(1000)', 'maxLength': 1000, 'minLength': 0, 'description': 'anything the admins should know, e.g. what you want to use Tempi for'}, 'email': {'type': 'string', 'format': 'email'}}, 'additionalProperties': False}
reschedule_booking_as_invitee
Reschedule a booking (invitee)
Moves a confirmed booking to `start` with the same hosts. Get valid times from get_available_slots with this `bookingId` and `token`. The calendar event is updated and its provider notifies attendees. Payment carries over. Not possible after `changeableUntil` (409 change_too_late).
