- `get\_account`: Who this key belongs to and whether a line exists yet.
- `search\_numbers`: Find available phone numbers in a US area code for a new line.
- `create\_line`: Set up the phone line: claim a number \(pick one from search\_numbers or just give an area code\), name the persona, and register the owner's mobile.

Brief it like a human assistant: who to ask for, what you want, acceptable fallbacks, what to do on voicemail. Set connect\_owner when the owner wants to be put through once a human is reached \(the line waits o
- `book\_reservation`: Reserve a table by phone: the line calls the venue, negotiates the time, answers the host's questions \(name, callback, email\), records policies, and never pays. Give the venue's phone number, party size, date/time, and the acceptable window or fallbacks. Returns reservation\_id and call\_id; read the

- `forward\_email`: Forward one received email to one of the line's own inboxes: its forwarding, notification or Bot inbox, or the owner's sign-in address \(defaults to the forwarding inbox\). It cannot forward to any other address, and a new inbox must be confirmed by its owner first.

CosVoice POSTs a JSON body with what\_to\_do plus the ids when th
- `set\_webhook`: Set \(or clear with an empty url\) the HTTPS webhook that receives call.completed, message.received, and email.received. Returns the signing secret once.
