• get_inbox

  Read an inbox: address, status, expiry, limits, and usage.

• list_messages

  List messages in an inbox, newest first. Pass after=<newest createdAt seen> to poll for only new mail.

• get_message

  Fetch one message with parsed text, HTML, and attachment download URLs.

• reply_to_message
