⚪start_rent(host, term_months, client, mandate)

Starts renting one listed name for a term (12, 6 or 1 month) and returns an approval_url for the human to open: they sign in (an email code, then a passkey or authenticator app), pass the identity check, sign the lease and pay by card, and the fixed-term lease starts on payment with no refunds after activation; names are rented for business or other commercial use only. Call it once the user has chosen the name and term. A rented or unheld name answers taken or not_listed with listed alternatives; a mandate (pre-authorized agent rent) is not available yet.
