Decart Realtime API
The realtime video transformation surface. A client opens a WebRTC session (LiveKit-managed transport) against a Lucy realtime model and streams camera or video frames in; the model returns transformed frames live, and the prompt or reference image can be swapped mid-session. Browser and mobile clients authenticate with short-lived ek_ client tokens minted server-side, optionally scoped to specific models, origins, and a maximum session duration.
