MixVoice API Overview

Introduction

The MixVoice API lets you integrate AI Audio, AI Image and AI Video generation into any application through a single, unified HTTP interface. Every endpoint is authenticated with an API key (Authorization: Bearer <api_key>) and returns standard JSON. Most generation endpoints are asynchronous tasks: you submit a request, get back a task_id, then poll for the result.

Unified auth — one API key for every capability
Async task model — submit → poll → get the result URL
Usage-based billing — per character / per second / fixed credits, with automatic refunds on failure
Hosted results — generated audio/image/video is returned as a ready-to-download URL

Base URL: https://api.aiclonevoicefree.com Every path is prefixed with it, e.g. POST https://api.aiclonevoicefree.com/api/v2/voice/clone

Capabilities

🎙️ AI Audio

Voice cloning & voice convert / timbre transfer — with emotion control.

🖼️ AI Image

Text-to-image & editing — GPT Image and Gemini Flash Image.

🎬 AI Video

Kling, Sora 2, Veo 3, Seedance, Vidu, Hailuo and more — 9 models.

Quickstart: AI voice cloning (3 steps)

# 1) Submit a voice-clone task with a reference audio + the text to synthesize; get a task_id
curl -X POST https://api.aiclonevoicefree.com/api/v2/voice/clone \
  -H "Authorization: Bearer sk_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "text": "Hello, this is speech cloned from my own voice.",
    "reference_audio_url": "https://oss.aiclonevoicefree.com/trump.wav",
    "model": "v1-real"
  }'
# → { "task_id": "xxxx", "status": "pending", "capability": "voice", "action": "clone", "created_at": 1780704348 }

# 2) Poll the status (one query endpoint shared by every capability)
curl https://api.aiclonevoicefree.com/api/v2/tasks/xxxx \
  -H "Authorization: Bearer sk_your_api_key"
# → { "status": "processing", ... }

# 3) Read audioUrl from the top level once completed
# → { "status": "completed", "audioUrl": "https://oss.aiclonevoicefree.com/tts/.../xxxx.wav", "providerUsed": "v1-async" }
