## Use this model from an AI agent

Atlas Cloud ships three first-party integration surfaces. All three authenticate
with the same API key via the `ATLASCLOUD_API_KEY` environment variable.

### MCP server

The official MCP server (`atlascloud-mcp`) exposes this model to any
MCP-compatible host — Claude Code, OpenAI Codex, Cursor, Gemini CLI, Goose,
Claude Desktop. One-line install:

```bash
# Claude Code
claude mcp add atlascloud -- npx -y atlascloud-mcp

# OpenAI Codex CLI
codex mcp add atlascloud -- npx -y atlascloud-mcp

# Gemini CLI
gemini mcp add atlascloud -- npx -y atlascloud-mcp

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

Then ask in plain English; the agent calls `atlas_generate_video` with `model: "minimax/hailuo-2.3/i2v-standard"`.
The server fetches each model's schema and validates parameters before submitting,
so invalid requests fail fast without spending credits.

### Agent Skills

`atlas-cloud-skills` is a portable skill package (API reference, code templates in
Python / Node.js / cURL, model IDs with pricing) for Claude Code, Cursor, Codex and
12+ other agents:

```bash
npx skills add AtlasCloudAI/atlas-cloud-skills
export ATLASCLOUD_API_KEY="your-api-key"
```

Skills docs: https://www.atlascloud.ai/docs/skills

### CLI

The `atlas` binary runs Atlas Cloud from a terminal or CI script. Async media jobs
are polled and downloaded automatically (use `--no-download` when a script only
needs the output URLs):

```bash
# Install (Homebrew, npm, or shell installer)
brew install AtlasCloudAI/tap/atlascloud
# npm install -g atlascloud-cli
# curl -fsSL https://raw.githubusercontent.com/AtlasCloudAI/cli/main/install.sh | sh

atlas auth login
atlas generate video minimax/hailuo-2.3/i2v-standard -p "Your prompt here"
```

CLI docs: https://www.atlascloud.ai/docs/cli

## HTTP API reference

- **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/hailuo-2.3/i2v-standard`


## API Information

This model can be used via our HTTP API or more conveniently via our client libraries.

  - Default: `"minimax/hailuo-2.3/i2v-standard"`

- **`prompt`** (`string`, _optional_):
  The positive prompt for the generation.

- **`image`** (`string`, _required_):
  The model generates video with the picture passed in as the first frame.Base64 encoded strings in data:image/jpeg; base64,{data} format for incoming images, or URLs accessible via the public network.

- **`duration`** (`integer`, _optional_):
  The duration of the generated media in seconds.
  - Default: `6`
  - Options: 6, 10

- **`enable_prompt_expansion`** (`boolean`, _optional_):
  The model automatically optimizes incoming prompts to enhance output quality. This also activates the safety checker, which ensures content safety by detecting and filtering potential risks.
  - Default: `false`



**Required Parameters Example**:

```json
{
  "model": "minimax/hailuo-2.3/i2v-standard",
  "image": ""
}
```


**Full Example**:

```json
{
  "model": "minimax/hailuo-2.3/i2v-standard",
  "prompt": "",
  "image": "",
  "duration": 6,
  "enable_prompt_expansion": false
}
```


### Output Schema

The API returns the following output format:


- **`created_at`** (`string`, _optional_):
  ISO timestamp of when the request was created (e.g., “2023-04-01T12:34:56.789Z”).

- **`has_nsfw_contents`** (`array[boolean]`, _optional_):
  Array of boolean values indicating NSFW detection for each output.

- **`id`** (`string`, _optional_):
  Unique identifier for the prediction, the ID of the prediction to get.

- **`model`** (`string`, _optional_):
  Model ID used for the prediction.

- **`outputs`** (`array[string]`, _optional_):
  Array of URLs to the generated content (empty 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
{
  "created_at": "",
  "has_nsfw_contents": [],
  "id": "",
  "model": "",
  "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": "minimax/hailuo-2.3/i2v-standard",
  "prompt": "",
  "image": "",
  "duration": 6,
  "enable_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)
```

### MiniMax Hailuo 2.3 — Image-to-Video (I2V) Standard

**Hailuo 2.3 I2V Standard** is MiniMax’s latest **image-to-video model**, designed to animate static images into smooth, cinematic video clips.

It combines natural motion synthesis, physical realism, and character consistency — enabling creators to bring still visuals vividly to life.

---

#### Why It Looks Great

* **Cinematic Motion** – Generates dynamic, camera-like movement such as panning, tracking, and zooming.

* **Physics-Aware Animation** – Simulates object dynamics (wind, light reflection, motion blur) with realistic precision.

* **Consistent Structure** – Preserves the original image’s composition, lighting, and character details.

* **Flexible Duration Options** – Choose between **6-second** and **10-second** clips.

* **Professional Fidelity** – Delivers filmic quality suitable for storytelling, ads, or product demos.

---

#### Limits and Performance

* **Input:** single reference image (JPEG / PNG)

* **Optional Input:** text prompt to guide motion and scene behavior

* **Duration:** **6 seconds** or **10 seconds**

* **Output resolution:** **1080p**

---

#### How to Use

1. Upload a **reference image** as your base frame.

2. (Optional) Add a **prompt** describing the desired motion or action.

   *Example:* “A motorcycle drives along a winding mountain road, camera panning smoothly to follow.”

3. Choose the **duration** (6 s or 10 s).

4. Click **Run** and wait for processing.

5. Download your animated video.

---

#### Pro Tips

* Keep prompts concise (1–2 sentences) to maintain visual stability.

* Use **camera verbs** like *pan*, *follow*, *zoom*, or *rotate* to define motion direction.

* For dynamic results, pick **10 s**; for previews or loops, choose **6 s**.

* The model preserves fine lighting and depth details — great for cinematic storytelling and concept visuals.
