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

- **`outputs`** (`array[string]`, _optional_):
  Array of URLs to the generated videos. Null when status is not completed.

- **`status`** (`string`, _optional_):
  Status of the task: created, processing, completed, or failed.

- **`urls`** (`object`, _optional_):
  Object containing related API endpoints.



**Example Response**:

```json
{
  "model": "ltx-2.3-quality/image-to-video",
  "created_at": "",
  "id": "",
  "outputs": [
    ""
  ],
  "status": "",
  "urls": {}
}
```


## 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": "ltx-2.3-quality/image-to-video",
  "prompt": "",
  "image_url": "",
  "num_frames": 121,
  "resolution": "landscape_16_9",
  "generate_audio": false,
  "seed": 0
}'

# 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)

LTX 2.3 Quality Image-to-Video

LTX 2.3 Quality Image-to-Video animates a static image into a high-quality video guided by a text prompt. It produces fluid, temporally consistent motion while preserving the visual style, colors, and composition of the source image.

🌟 Key Features

🖼 Image-Driven Animation

Breathe life into any static image — photos, illustrations, or AI-generated artwork — with prompt-guided motion and cinematic quality.

🔊 Optional Audio Generation

Optionally generate synchronized audio alongside the video in a single request.

📐 Multiple Resolution Presets

Six aspect ratio presets to match any layout requirement.

🔁 Reproducible Results

Pin a seed value to reproduce or iterate on a specific generation.

⚙️ Parameters

Parameter	Required	Description
`prompt`	✅	Text description of the desired motion and style. Maximum 2,000 characters.
`image_url`	✅	URL of the input image to animate. Supported: jpg, jpeg, png, webp, gif, avif.
`num_frames`	❌	Number of frames to generate (default: `121`). Must be a multiple of 8 plus 1.
`resolution`	❌	Output video resolution preset (default: `landscape_16_9`). See options below.
`generate_audio`	❌	Whether to generate accompanying audio (default: `false`).
`seed`	❌	Random seed for reproducibility. Omit for random results.

Resolution Options

Value	Description
`square_hd`	Square HD (1024×1024)
`square`	Square (512×512)
`portrait_3_4`	Portrait 3:4
`portrait_9_16`	Portrait 9:16
`landscape_4_3`	Landscape 4:3
`landscape_16_9`	Landscape 16:9

Frame Count Guide

`num_frames`	Approximate Duration (24fps)
25	~1 second
81	~3.4 seconds
121	~5 seconds
161	~6.7 seconds
257	~10.7 seconds

💲 Pricing

Billed at $0.0024075 per megapixel of generated video data (width × height × num_frames), rounded upward.

Example: landscape_16_9 (1280×720) at 121 frames ≈ 112 MP ≈ $0.27

💡 Prompt Tips

The flowers sway gently in the breeze, petals catching the sunlight, soft bokeh background slowly shifting.

Focus the prompt on motion: "camera slowly zooms in", "gentle wind moves the trees", "waves lap at the shore".
Keep the prompt consistent with the image content — contradictory prompts produce unstable motion.
Use short, specific motion descriptions for best results; long narrative prompts can reduce temporal coherence.
Fix seed when tweaking prompt wording to isolate motion changes.

🎯 Use Cases

Product Animation — Animate product photos for e-commerce with subtle, professional motion.
Portrait & Character Animation — Add lifelike motion to portraits, illustrations, or avatars.
Landscape & Nature — Bring scenic photos to life with realistic environmental motion.
Art & Illustration — Animate concept art, paintings, and graphic design assets.
Social Media Content — Transform static posts into engaging short video clips.

📝 Notes

Both prompt and image_url are required.
num_frames must satisfy: (num_frames - 1) % 8 == 0 (e.g. 25, 33, 41, 81, 121, 161, 257).
Task status values: created, processing, completed, failed.
Generated video URLs are returned in outputs once status is completed.
