Overview

Searching for a Duix Avatar API or a hosted alternative to self-managed digital-human stacks? KeyoAPI exposes Duix-Avatar as an async talking-avatar API: feed a face video plus driving audio, get lip-sync and expressions back as a render job. This is the API path for product teams — not a consumer Duix app. Build the loop on one prepaid key: generate speech with CosyVoice3 / Qwen3-TTS / IndexTTS-2, then drive Duix-Avatar. Per-second pricing (~$0.00685) maps to output length; confirm on the full pricing list. Cap max duration, show queue ETA, and moderate deepfake abuse. Prefer InfiniteTalk when you start from a still photo plus audio. Endpoint: POST /v1/async/videos/audio-video-to-video with model=Duix-Avatar, then GET /v1/task/{id}.
