## 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/t2v-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/t2v-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/t2v-standard`


## 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

The API accepts the following input parameters:

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

- **`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: `true`



**Required Parameters Example**:

```json
{
  "model": "minimax/hailuo-2.3/t2v-standard",
  "prompt": ""
}
```


**Full Example**:

```json
{
  "model": "minimax/hailuo-2.3/t2v-standard",
  "prompt": "",
  "duration": 6,
  "enable_prompt_expansion": true
}
```


### 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/t2v-standard",
  "prompt": "",
  "duration": 6,
  "enable_prompt_expansion": true
}'

# 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)
```

### Hailuo 2.3 Standard

**Hailuo 2.3 Standard** is the latest generation of **AI video creation models**, featuring advanced physics rendering and cinematic-grade scene transitions.

Built for both creators and professionals, it combines **high fidelity**, **reliability**, and **cost efficiency**, outperforming many closed or premium video generation systems.

---

#### Why It Looks Great

* **Flexible Duration Options** — Generate **6-second** or **10-second** cinematic clips.

* **Realistic Motion & Physics** — Handles complex dynamics such as **water flow, debris movement, and camera shake** with physical consistency.

* **Seamless Scene Transitions** — Produces smooth, natural visual transitions without abrupt cuts.

* **Reliable Consistency** — Reproducible results across identical prompts for precise creative control.

* **Professional Quality, Affordable Price** — Achieve production-level results at a fraction of competitors’ cost.

---

#### Limits and Performance

* **Output resolution:** fixed at **1080p**

* **Maximum clip length per job:** **10 seconds**

* **Duration options:** **6 s** or **10 s**

* **Processing time:** approximately **30 – 90 seconds** per clip (depending on scene complexity and queue load)

---

#### Billing Rules

* **Flat-rate billing per clip** (6 s or 10 s).

* **No prorated pricing** — shorter clips are charged at the full duration tier.

* **Total cost = number of clips × rate.**

---

#### How to Use

1. Write a **prompt** describing the desired scene, lighting, motion, or camera movement.

2. Choose your **duration** (6 s or 10 s).

3. Submit the job and wait for processing.

4. **Download** your completed video once ready.

---

#### Pro Tips for Best Quality

* Craft **cinematic prompts** that specify camera angles, lighting style, and mood.

* Use **dynamic verbs** (e.g., *zoom in*, *pan left*, *fly over*) to introduce camera motion.
