  • cancel_calendar_inviteCancel Calendar Invitecan change or delete data

    Cancel an invitation you sent, taking it off the attendees' calendars. The cancellation is matched to the original event by `uid`, which send_calendar_invite returned.

Args: inbox_id: The inbox that sent the original invitation to: The attendees to notify (comma-separated), as originally invited uid: The calendar_uid returned when the invitation was sent title: The event title, as originally sent start: The event's original start time, ISO 8601 sequence: Must be higher than the…

  • create_calendar_eventCreate Calendar Event

    Put an event on the inbox's calendar, and optionally send it to the attendees as a real invitation. This is the agent's own calendar: the event shows up in list_calendar_events and on the calendar feed a human may have subscribed to. With send_invites=True the attendees also receive a proper iCalendar invitation (Accept/Decline in their mail client), and their answers update the event as they come back. Prefer this over send_calendar_invite when the agent should keep track of the event afterwards. Args: inbox_id: The inbox whose calendar gets the event (and sends the invites) title: …

  • reply_to_messageReply to Message

    Reply to a message. Threading headers are set automatically. Works on messages you sent as well as ones you received.

  • send_calendar_inviteSend Calendar Invite

    Send a real calendar invitation: Accept/Decline in the recipient's mail client, and the event on their calendar. Use this rather than attaching an .ics file. An attached .ics is only a file the recipient has to open by hand; it does not create the invitation, and an agent on the other end has to guess what the attachment is. This puts the event in the message itself, where mail clients and other agents look. Returns the invite's uid. Keep it: changing or cancelling the meeting needs it. Args: inbox_id: The inbox to send from to: Attendee email addresses (comma-separated for multiple…

  • send_emailSend Email

    Send an email from a Dead Simple Email inbox

  • sign_in_with_inboxSign In With Inbox

    Sign in to a third-party app using this inbox as the agent's identity (Sign in with Dead Simple, an OpenID Connect provider at https://id.deadsimple.email). Use when an app offers "Sign in with Dead Simple" or any OIDC login whose authorization URL starts with https://id.deadsimple.email/authorize. Pass that URL exactly as the app produced it. The app receives the inbox's address as the account email, so verification emails land in this inbox. With follow=true the redirect back to the app is fetched so the login completes; final_url and final_status show where it landed.

  • wait_for_emailWait for Emailread-only

    Block until a NEW inbound email arrives in the inbox, then return it. Use for signup/verification flows: trigger the action that sends the email, then call this to receive it. Only emails arriving after this call count.
