Pass api_key as the `api_key` argument on every later Primitive call, exactly as returned. address is a domain, not a mailbox; sender_address (such as agent@pink-ram.primitive.email) is the mailbox sendEmail sends from. can_send_to lists the only recipients the account may email. If this host already has an inbox, it comes back with existing_account: true and a message: report it as their existing inbox. Without an api_key the user must sign in. Creating the account accepts Primitive's terms of service for the user: tell them. Result: org_id, address (null without a managed inbox), existing_account; sender_address when address is set; api_key and can_send_to unless the key cannot be returned; for a new account, plan, limits, upgrade and funding; for an existing one, message.",
