**APIs profiled:** 4

Uberduck is an AI voice platform whose public REST API converts text into 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 LiveKit tokens for real-time conversational AI voice calls. The API is HTTPS request/response with Bearer API-key authentication. It is self-serve but gated behind a paid plan - API access is a feature of the Creator plan and above. Uberduck's earlier AI music / rap-vocals API surface is no longer part of the published API; the current documented product (OpenAPI version 0.1.0) is focused on text-to-speech, voices, and conversational voice.
