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-developer/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",

LLM-Friendly Prompt Template

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

> MiniMax H3-Developer self-hosted image-to-video: animate a first-frame image (optionally a last frame) driven by a text prompt, with generated audio. Supports 480P/768P/2K.


## 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-developer/image-to-video`


## API Information

This model can be used via our HTTP API or more conveniently via our client libraries.
See the input and output schema below, as well as the usage examples.


### Input Schema

- **`prompt`** (`string`, _required_):
  The text prompt describing the motion / action for the video.

- **`image`** (`string`, _optional_):
  First frame of the video. Public URL or Base64. Formats: png, jpeg, jpg, webp.

- **`end_image`** (`string`, _optional_):
  Optional last frame of the video. Public URL or Base64. Formats: png, jpeg, jpg, webp.

- **`resolution`** (`string`, _required_):
  The resolution of the generated video.

  The duration of the generated video in seconds.
  - Default: `8`
  - Options: 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15

- **`ratio`** (`string`, _optional_):
  The aspect ratio of the generated video. Use 'adaptive' to let the model choose.
  - Default: `"adaptive"`
  - Options: "adaptive"

- **`prompt_expansion`** (`boolean`, _optional_):
  Whether to expand the prompt for better results.
  - Default: `false`



**Required Parameters Example**:

MiniMax H3-Developer Image-to-Video

MiniMax H3-Developer Image-to-Video brings a static image to life — with sound. Provide a first-frame image — and, optionally, a last frame — plus a prompt describing the motion. Generate native 480P or 768P video, or select an ESR tier to enhance the output to a 1080P, 1440P, or 4K short edge, complete with a synchronized soundtrack generated from the described scene.

Why Choose This?

Image-driven generation Animate any image with natural, controllable motion.
Native audio A matching soundtrack (ambient sound, effects, and music) is generated alongside the video — no separate audio input needed.
First & last frame control Set the opening frame, and optionally pin the closing frame for a precise transition.
Enhanced resolution output Generate native 480P or 768P video, or use ESR for a 1080P, 1440P, or 4K short edge.
Selectable duration Produce 5–15s clips.

Parameters

Parameter	Required	Description
prompt	No	Text description of the desired motion and action
image	Yes	First frame of the video (public URL)
end_image	No	Last frame of the video (public URL)
resolution	No	Video resolution. Available options: `768P` (default), `480P`, `1080p-esr`, `1440p-esr`, `4k-esr`. ESR tiers generate a native 768P source and enhance the output to the requested short edge.
duration	No	Duration of the generated video in seconds. Integer between 5 and 15 (default 5)
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.

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, action, and the sound of the scene.
Set resolution and duration — balance quality against generation speed.
(Optional) Tune seed and steps — fix the seed for reproducibility, raise steps for quality.
Run — submit and download your video.

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, with matching sound.

Pro Tips

Be specific about movement direction, speed, and camera angles.
Describe the scene's audio (traffic, music, crowd) to shape the generated soundtrack.
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.

Notes

The first-frame image is required; the prompt is optional but strongly recommended.
The last-frame image is optional; when provided, the clip ends on it.
ESR tiers add an enhancement stage after native generation and may take longer than native resolutions.
Ensure image URLs are publicly accessible.
Generation is asynchronous — submit, then poll for the finished video.

MiniMax H3-Sol Text-to-Video — Generate video directly from a text prompt.
MiniMax H3-Sol Reference-to-Video — Keep a subject consistent from reference materials.
