Report who the person is currently acting for on Gemalli: role, interface language and, when signed in, the company they represent and their plan. An anonymous person is a valid answer and comes back as a guest, not an error. If the person signed in after talking to you anonymously, previous_guest carries the identifier of that earlier conversation so you can carry the history over, and linked_at separates a link you have not seen before from one you have already handled. credits tells whether platform credits are on (enabled), the balance and total granted when signed in, buy_url (null means no payment page yet: send the person to Office Live) and action_costs, the only map from a tool to its action and price: call something free only when its credits is 0, never offer an action whose credits is null. wallets carries one entry per credit kind with its balance and low: low true means that kind is running out and the panel should show the remaining-credits note. Every paid answer carries the same wallets, freshly counted after the charge — prefer those over this first reading. Never returns another party's data and never returns secrets.
