        Gets information about the owner of a given access token. 
        
        Note that, as with the rest of the Client-Server API, 
        Application Services may masquerade as users within their 
        namespace by giving a ``user_id`` query parameter. In this 
        situation, the server should verify that the given ``user_id``
        is registered by the appservice, and return it in the response 
        body.
