Level Mobile Application Backend
The undocumented HTTPS backend the Level Home iOS and Android applications talk to. It is an AWS API Gateway fronted service that returns a `{"message": "..."}` JSON error envelope and an `x-request-id` correlation header on every response. A small set of paths is publicly advertised through the Apple App Site Association and Android asset links files it serves from /.well-known — /invite/{uuid}, /pass/{id}, /verify/{token}, /recover/{token} and /franklin/in-home/opt-in/{id} — used for universal-link invitations, guest passes and account recovery. There is no public specification, no developer signup and no documented authentication.
