The API provides session-based login using the `/api/v1/auth/login` and `/api/v1/auth/logout` options. If authentication is not enabled, these endpoints return a JSON `message` of `Authentiation is disabled` and HTTP code 200.
For one-time authentication, the `token` value can be specified to any API endpoint. This is only checked if there is no valid session already established. If authentication is enabled, there is no valid session, and no `token` value is specified, the API will return a JSON `message` of `Authentication required` and HTTP code 401.
