Duix Avatar API & AI Avatar Video Generator — KeyoAPI

Looking for a Duix Avatar API without running your own render farm? KeyoAPI hosts Duix-Avatar (audio+video → talking face) and InfiniteTalk (image/audio → talking head) as async jobs — generate speech with IndexTTS-2 / CosyVoice3 / Qwen3-TTS on the same key, then render.

Duix Avatar API & AI Avatar Video Generator is a model-family pricing lane on KeyoAPI — a prepaid AI API gateway where one Bearer key and one wallet ($1 = 500,000 quota units) cover chat, speech, vision, OCR and video models.

Indicative figures for planning. Confirm live Keyo sell rates on interactive Model Square or the static pricing list.

Productize the loop, not a single model

Typical product loop: draft script → TTS (optionally cloned) → avatar render → CDN cache. Cap max duration, show queue ETA, and moderate deepfake abuse. Try/buy each model from the pricing page (Model Square) after the sign-up page — no separate upload playground.

Rates and pipeline

Duix Avatar API (downstream use): product teams often search “duix avatar” when they need a talking-face render they can meter in SaaS — Keyo exposes that as model=Duix-Avatar on an async video endpoint, not as a consumer editor.

This is the API path, not a consumer app: prepaid metering, OpenAI-style auth for adjacent chat and speech, async task polling for renders.

Indicative rates: Duix-Avatar ~$0.0068 per second of output; InfiniteTalk ~$0.342 per request. Confirm the Duix-Avatar model page and the InfiniteTalk model page before volume. Pick Duix when you have driving video; pick InfiniteTalk when you start from a still spokesperson photo.

How to call: async video endpoints with model=Duix-Avatar or InfiniteTalk, then GET /v1/task/{id}. Speech side: the TTS API guide and the voice cloning API guide. Model guides under the Duix-Avatar model page and the InfiniteTalk model page.

Likeness rights and abuse prevention are your product’s responsibility — rate-limit, log, and require consent flags before queueing.

curl https://www.keyoapi.xyz/v1/async/videos/image-to-video \
  -H "Authorization: Bearer $KEYO_API_KEY" \
  -F model=InfiniteTalk \
  -F "prompt=natural talking-head delivery" \
  -F cond_video=@./portrait.png \
  -F cond_audio=@./voice.wav
# then: GET /v1/task/{id}

Get started in five steps

1. Create an account — new users receive $10 of gift credit for prototyping.
2. Create an API key in the console.
3. Point your OpenAI SDK at https://www.keyoapi.xyz/v1 with the model ID from this page, or call the dedicated REST path from the API handbook.
4. Track spend in the console Wallet — $1 equals 500,000 quota units, and gift credit burns before recharged balance.
5. Set a per-key spending cap before wiring production traffic.

A verified first call is the acceptance test for the setup: the response should carry the payload shape documented in the handbook, the Wallet ledger should show a deduction in quota units (500,000 units = $1), and repeated calls should deduct linearly at the listed rate. Any mismatch usually means the model ID or endpoint is wrong — check both against the pricing list before debugging client code.
