Uberduck Conversational API

openapi: 3.0.3
info:
  title: Uberduck Text To Speech Conversational API
  description: The Uberduck API converts text to natural-sounding speech across a catalog of voices and provider-backed models (AWS Polly, Google Cloud, Azure), lists and filters those voices, creates instant zero-shot voice clones from reference audio, and mints short-lived LiveKit tokens for real-time conversational AI voice calls. All requests are HTTPS request/response and authenticate with a Bearer API key generated in the Uberduck account settings. API access is a paid feature available on the Creator plan and above. This document is transcribed from Uberduck's published OpenAPI (https://api.uberduck.ai/openapi.json, version 0.1.0) and its Swagger UI at https://api.uberduck.ai/docs.

      description: Generate a LiveKit token for a real-time AI voice call. Returns the LiveKit server URL, a room name, and a JWT participant token the client uses to join the room. The realtime media transport itself is provided by LiveKit (WebRTC), not by Uberduck's own HTTP API.
