Install

Install the required package for your language.

pip install requests

Authentication

All API requests require authentication via an API key. You can get your API key from the Atlas Cloud dashboard.

export ATLASCLOUD_API_KEY="your-api-key-here"

HTTP Headers

import os

API_KEY = os.environ.get("ATLASCLOUD_API_KEY")
headers = {
    "Content-Type": "application/json",
    "Authorization": f"Bearer {API_KEY}"
}

Keep your API key secure

Never expose your API key in client-side code or public repositories. Use environment variables or a backend proxy instead.

Submit a request

import requests

url = "https://api.atlascloud.ai/api/v1/model/generateVideo"
headers = {
    "Content-Type": "application/json",
    "Authorization": "Bearer $ATLASCLOUD_API_KEY"
}
data = {
    "model": "your-model",
    "prompt": "A beautiful landscape"
}

response = requests.post(url, headers=headers, json=data)
print(response.json())

Submit a Request

Submit an asynchronous generation request. The API returns a prediction ID that you can use to check the status and retrieve the result.

POST/api/v1/model/generateVideo

Request Body

import requests

url = "https://api.atlascloud.ai/api/v1/model/generateVideo"
headers = {
    "Content-Type": "application/json",

}

data = {
    "model": "minimax/h3-max/image-to-video",
    "prompt": "A beautiful sunset over the ocean with gentle waves"
}

response = requests.post(url, headers=headers, json=data)
result = response.json()

print(f"Prediction ID: {result['data']['id']}")
print(f"Status: {result['data']['status']}")

Response

{
  "code": 200,
  "data": {
    "id": "pred_abc123",
    "status": "processing",
    "model": "model-name",

# minimax/h3-max/image-to-video

> MiniMax H3 Max image-to-video: animate a first-frame image (optionally with a last frame) driven by a text prompt. Supports 480P、768P, 5-15s.


## Overview

- **Submit endpoint (POST)**: `https://api.atlascloud.ai/api/v1/model/generateVideo` — start an async generation; returns a `prediction_id`
- **Poll endpoint (GET)**: `https://api.atlascloud.ai/api/v1/model/prediction/{prediction_id}` — poll this until the prediction finishes
- **Model ID**: `minimax/h3-max/image-to-video`


## API Information

## Usage Examples

### cURL

```bash
# Step 1: Start generation (async)
curl -X POST "https://api.atlascloud.ai/api/v1/model/generateVideo" \
  -H "Authorization: Bearer $ATLASCLOUD_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "minimax/h3-max/image-to-video",
  "prompt": "",
  "image": "",
  "end_image": "",
  "resolution": "768P",
  "duration": 8,
  "ratio": "adaptive",
  "prompt_expansion": false
}'

# Response will contain: {"code": 200, "data": {"id": "prediction_id", "status": "processing"}}

# Step 2: Poll for result (replace {prediction_id} with the id returned above)
curl -X GET "https://api.atlascloud.ai/api/v1/model/prediction/{prediction_id}" \
  -H "Authorization: Bearer $ATLASCLOUD_API_KEY"

# Keep polling until status is "completed", "succeeded" or "failed"
# When completed, outputs will contain the generated content URL(s)

A cinematic sci-fi spacecraft races through a massive golden cosmic vortex, following the curvature of an enormous glowing ring. The spacecraft accelerates rapidly into the distance, leaving long trails of white-blue engine light behind it. Golden energy streams and luminous particles sweep past the camera at extreme speed, creating powerful parallax and a strong sense of motion. The camera dynamically tracks alongside and slightly behind the spacecraft, then slowly pushes forward as the ship dives deeper into the vortex. Massive arcs of golden light bend across the dark universe, while clouds of cosmic dust and sparkling particles swirl around the scene. Epic scale, dramatic perspective, high-speed motion, volumetric lighting, realistic spacecraft details, cinematic sci-fi atmosphere, deep black space, gold and white color palette, intense light contrast, anamorphic composition, subtle motion blur, IMAX-style cinematography, ultra-detailed, photorealistic, 4K.

MiniMax H3 Max Image-to-Video

MiniMax H3 Max Image-to-Video brings a static image to life at speed. Provide a first-frame image — and, optionally, a last frame — plus a prompt describing the motion, and the model generates a complete 24fps clip with audio that starts (and optionally ends) exactly on your images. A 5-second 768P clip renders in under 3 seconds, so you can try several motion directions in the time a single render usually takes.

Why Choose This?

Near-instant generation A 5s 768P clip in under 3 seconds; 15s clips in about 15 seconds.
Image-driven generation Animate any image with natural, controllable motion.
First & last frame control Set the opening frame, and optionally pin the closing frame for a precise transition.
Audio included Every clip is generated as complete audio-video at 24fps — no separate scoring or sound pass.
Aspect ratio from your image Automatically determined by the input image (always adaptive).
Selectable duration Produce 5–15s clips at 480P or 768P.

Parameters

Parameter	Required	Description
prompt	Yes	Text description of the desired motion and action
image	Yes	First frame of the video (public URL or Base64)
end_image	No	Last frame of the video (public URL or Base64)
resolution	Yes	Video resolution. Available options: `480P`, `768P`. Default `768P`
duration	Yes	Duration of the generated video in seconds. Available options: 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15. Default 8
ratio	No	Aspect ratio of the generated video. For image-to-video, the aspect ratio is determined by the input image and is always `adaptive`; passing any other value is ignored.
prompt_expansion	No	Enable AI prompt expansion via H3 Context-IR. When `true`, your prompt is first expanded into a rich, structured description (shot, soundscape, music) before generation, and an additional per-token Context-IR fee applies. Default `false`: the prompt is used as-is with no extra charge.
callback_url	No	HTTPS URL notified whenever the task status changes, so you can react to completion without polling. Requires a one-time verification handshake — see Task Status Callbacks below.

Task Status Callbacks (`callback_url`)

When you supply a callback_url, the MiniMax server notifies it on every task status change, so you don't have to poll for the result.

Verification handshake — right after the task is created, the server first sends a verification request to your URL containing a challenge field. Your endpoint must return the challenge value unchanged, within 3 seconds, to complete verification.
Status pushes — once verification succeeds, the server sends a POST to your URL every time the task status changes. The push body has the same structure as the Query Task (task status) response.

Callback status values: queued, running, succeeded, failed, cancelled.

The callback_url must be a publicly reachable HTTPS endpoint.

How to Use

Upload your first-frame image — the video will start from this image.
(Optional) Upload a last-frame image — the video will end on this image.
Write your prompt — describe the motion, camera movement, and action.
Set resolution and duration — pick 480P or 768P, and any length from 5s to 15s.
Run — submit and download your video. The aspect ratio follows your input image automatically.

Best Use Cases

Photo Animation — Bring portraits, landscapes, and product images to life.
Start/End Transitions — Morph smoothly from one image to another.
Marketing & Ads — Turn product photos into dynamic promotional videos.
Storytelling — Animate illustrations and artwork for narratives.

Pro Tips

Be specific about movement direction, speed, and camera angles.
When using a last frame, keep the two images' aspect ratios close for a clean transition.
Use high-quality source images for better video results.
Describe environmental effects (wind, smoke, dust) for more immersive motion.

Notes

Both prompt and first-frame image are required.
The last-frame image is optional; when provided, the clip ends on it.
Supported image formats: png, jpeg, jpg, webp. Ensure image URLs are publicly accessible.
Supported durations between 5s and 15s, at 24fps with audio.
Resolution is limited to 480P and 768P — 2K is not available on H3 Max.
Keyframe interpolation and multimodal references (reference image / video / audio) are not supported.
Generation is asynchronous — submit, then poll for the finished video.
