MiniMax H3 API: Python SDK for AI Video Generation

Python SDK for the MiniMax H3 API on Muapi. Generate video from text, animate a still image, or guide a new video with image, video, and optional audio references using one API key.

Installation

pip install minimax-h3-api

Or install from source:

git clone https://github.com/Anil-matcha/MiniMax-H3-API.git
cd MiniMax-H3-API
pip install -e .

Set your Muapi API key:

export MUAPI_API_KEY=your_muapi_api_key

Quick start

from minimax_h3_api import MiniMaxH3API

api = MiniMaxH3API()

task = api.text_to_video(
    "A cinematic tracking shot of a silver sports car driving through a rain-soaked city at night",
    aspect_ratio="16:9",
    resolution="2k",
    duration=5,
)

result = api.wait_for_completion(task["request_id"])
print(result["outputs"][0])

Workflows

Text to video

task = api.text_to_video(
    prompt="A lone astronaut walking through a field of bioluminescent flowers, slow camera dolly in"
)

Image to video

task = api.image_to_video(
    prompt="The camera slowly pushes in as a warm breeze moves through the subject's hair",
    image_url="https://example.com/source-image.jpg",
    last_image_url="https://example.com/final-frame.jpg",
    duration=5,
)

Reference to video

task = api.reference_to_video(
    prompt="Use the references to create a cinematic product reveal with a slow camera orbit",
    reference_images=["https://example.com/product.jpg"],
    reference_videos=["https://example.com/motion-reference.mp4"],
    reference_audios=["https://example.com/soundtrack.mp3"],
    aspect_ratio="16:9",
    resolution="2k",
    duration=5,
)

At least one reference_images or reference_videos URL is required. Audio references are optional and cannot be used alone.

First and last frame compatibility alias

Existing integrations can continue using first_last_frame(). It now maps to the current image-to-video endpoint with image_url and last_image_url; new code should call image_to_video() directly.
