# Wan 3.0 Text-to-Video — Atlas Cloud API

> All-in-one Wan3.0 renderer: cinematic, hyper-real video from a text prompt, up to 30s with smart-duration and adaptive aspect ratio.

This is the machine-readable API reference for **Wan 3.0 Text-to-Video** on Atlas Cloud,
a unified API platform for 400+ AI models across text, image, video, audio and 3D.

- **Model ID**: `alibaba/wan-3.0/text-to-video`
- **Built by**: Alibaba
- **Modality**: Video
- **Model page**: https://www.atlascloud.ai/models/alibaba/wan-3.0/text-to-video
- **API key**: https://www.atlascloud.ai/console/api-keys
- **Docs**: https://www.atlascloud.ai/docs

## Pricing on Atlas Cloud

- $0.05 per second of generated video
- Pay-as-you-go. No minimum spend, no subscription required.

> **These are the authoritative Atlas Cloud rates for this model.** Any price that
> appears in the vendor description further down refers to a different platform or
> a different model variant and does not apply here.

## 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: "alibaba/wan-3.0/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 alibaba/wan-3.0/text-to-video -p "Your prompt here"
```

  - Default: `true`

- **`seed`** (`integer`, _optional_):
  The random seed to use for the generation. -1 means a random seed will be used.



**Required Parameters Example**:

```json
{
  "model": "alibaba/wan-3.0/text-to-video",
  "prompt": ""
}
```


**Full Example**:

```json
{

## About this model

_Vendor-supplied description. Any pricing or endpoint mentioned below refers to_
_other platforms — use the Atlas Cloud values above._

#### Wan 3.0 Text-to-Video

**Wan 3.0** is Alibaba's all-in-one "super-real world renderer" — a single model that turns a text prompt into a cinematic, hyper-realistic clip with native audio. It renders not just motion but the texture of a scene, fine human detail, and even structured on-screen information (UI, text, animation) with pixel-level fidelity.

#### Why Choose This?

-   **Native long-form generation** Produce clips up to 30 seconds in a single pass — richer narrative, more creative freedom.

-   **Smart duration** Let the model pick the ideal length from your intent and content (`duration = -1`).

-   **Hyper-real rendering** Film-grade texture, lighting, and lifelike movement from a plain-text description.

-   **Sound on by default** The output includes a synchronized audio track; toggle it off at no extra cost.

-   **Flexible aspect ratios** adaptive, 16:9, 4:3, 1:1, 3:4, or 9:16.

#### Parameters

| Parameter | Required | Description |
| --- | --- | --- |
| prompt | Yes | Text description of the scene, subject, and action (up to 5000 chars) |
| resolution | No | Output quality: 1080P (default), 720P, 480P |
| duration | No | Video length in seconds: 5 (default), 2–30. Pass -1 for smart-duration |
| ratio | No | Aspect ratio: adaptive (default), 16:9, 4:3, 1:1, 3:4, 9:16 |
| audio | No | Whether the output has an audio track: true (default) / false. Same price either way |

#### How to Use

1.  **Write your prompt** — describe scene, subject, lighting, motion, and any dialogue.
2.  **Set resolution** — higher for quality, lower for faster generation.
3.  **Choose an aspect ratio** — match your target platform, or use adaptive.
4.  **Adjust duration** — 2–30s, or -1 to let the model decide.
5.  **Run** — submit and download your video.
