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"
)

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",
)

First and last frame

task = api.first_last_frame(
    prompt="A smooth orbit around the subject as daylight shifts into a cinematic sunset",
    first_frame_image="https://example.com/first-frame.jpg",
    last_frame_image="https://example.com/last-frame.jpg",
)
