MiniMax H3 API SDKs for JavaScript, Python, Ruby, Go, Java, and PHP on RunAPI.

Typed SDKs for MiniMax H3 video generation through RunAPI. The public minimax-h3-sdk repository groups the JavaScript, Python, Ruby, Go, and Java packages. PHP is released from the split minimax-h3-php Composer repository.

MiniMax H3 exposes two resources:

• textToVideo / text_to_video for prompt-only requests and requests with reference images, videos, or audio.
• imageToVideo / image_to_video for first-frame, last-frame, or first-and-last-frame requests.

For PHP, use runapi-ai/minimax-h3 from the split Composer repository.

import { MiniMaxH3Client } from '@runapi.ai/minimax-h3';

const client = new MiniMaxH3Client();

const result = await client.textToVideo.run({
  model: 'minimax-h3',
  prompt: 'A cinematic tracking shot through a rain-soaked city',
  aspect_ratio: '16:9',
});

console.log(result.videos[0].url);

Reference media uses the same textToVideo resource:

const task = await client.textToVideo.create({
  model: 'minimax-h3',
  prompt: 'Keep the character and voice consistent in a new scene',
  reference_image_urls: ['https://cdn.runapi.ai/public/samples/image.jpg'],
  reference_audio_urls: ['https://cdn.runapi.ai/public/samples/voice.mp3'],
  aspect_ratio: 'adaptive',
});

Use create to submit and return a task id, get to read current status, or run to submit and poll to completion. In request handlers, prefer create with a callback or later polling.

Returned file URLs are temporary. Download generated files into durable storage within the retention window.
