## 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: "kwaivgi/kling-v3.0-pro/text-to-video"`.
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 kwaivgi/kling-v3.0-pro/text-to-video -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**: `kwaivgi/kling-v3.0-pro/text-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

  - Options: "16:9", "9:16", "1:1"

- **`cfg_scale`** (`number`, _optional_):
  Flexibility in video generation; The higher the value, the lower the model's degree of flexibility, and the stronger the relevance to the user's prompt.
  - Default: `0.5`
  - Min: 0
  - Max: 1

- **`sound`** (`boolean`, _optional_):
  Whether sound is generated simultaneously when generating a video.

_other platforms — use the Atlas Cloud values above._

#### Kling V3.0 Pro Text-to-Video

Kling V3.0 Pro is Kuaishou's Kling 3.0 text-to-video model in Professional mode (1080P output). Describe a scene and get high-fidelity cinematic video with native synchronized audio, 3–15 second duration, and single-shot or multi-shot (storyboard) generation.

#### Why Choose This?

- **Pro-tier quality** 1080P output with more detail and smoother motion than Standard mode.
- **Flexible duration** Any length from 3 to 15 seconds, in 1-second steps.
- **Multi-shot storyboards** Up to 6 shots in one video, each with its own prompt and duration, or let the model split the shots automatically.
- **Native audio** Sound is generated together with the video and is on by default.
- **Kling 3.0 generation** Better motion quality and visual fidelity than Kling 2.6.

#### Parameters

| Parameter | Required | Description |
| --- | --- | --- |
| prompt | Conditional | Text description of the scene, subjects, motion and camera. Max 2,500 characters. Required unless `multi_shot` is on with `shot_type` = `customize`, in which case it is ignored. |
| negative_prompt | No | What to avoid in the video. Max 2,500 characters. Kling recommends also writing exclusions as negative sentences in the prompt. |
| multi_shot | No | Generate a multi-shot video (default: `false`). |
| shot_type | Conditional | Required when `multi_shot` is `true`. `customize`: you define every shot in `multi_prompt`. `intelligence`: the model splits `prompt` into shots. |
| multi_prompt | Conditional | Required when `shot_type` is `customize`. 1–6 shots, each `{index, prompt, duration}`. Each shot prompt can be up to 512 characters, each shot lasts at least 1 second, and the shot durations must add up to `duration`. |
| duration | No | Video length in seconds: any integer from 3 to 15 (default: `5`). |
| aspect_ratio | No | `16:9` (default), `9:16` or `1:1`. |
| cfg_scale | No | Prompt adherence, 0–1 (default: `0.5`). Higher values follow the prompt more strictly. Kling's offici
