Telegram MTProto
MTProto is Telegram's own binary transport and encryption protocol for building full-featured client apps, distinct from the simplified Bot API — developers register an application for an api_id/api_hash pair, then authorize as a real user via phone-number login (SMS/QR/2FA), not a redirect-based OAuth flow. It's free to use, but as a raw binary socket protocol rather than a browser-facing HTTP/JSON API, there is no conventional Origin-header CORS surface to probe; left unknown rather than guessed.
