# Wan2.6 動画生成

> Generate high-quality videos using Alibaba Cloud Wan2.6 model — supports text-to-video, image-to-video and reference-video

> [!NOTE]
>
> **中国本土のユーザー向け：** 中国本土のユーザーは `https://toapis.cn` を API エンドポイント（Base URL）としてご利用ください。本ドキュメント内の例では `https://toapis.com` を `https://toapis.cn` に置き換えてください。

* Alibaba Cloud Wanxiang video generation model
* Supports **three modes**: Text-to-Video, Image-to-Video, and Reference Video (r2v)
* Server automatically routes to the appropriate upstream model based on your request parameters
* Supports 720p/1080p resolution, 5/10/15 second duration
* Audio is always included in the generated output

> [!WARNING]
>
> **Important Change**: For better performance and cost control, we no longer support passing base64 image data directly in `image_urls`. Please use the [Upload 画像API](https://docs.toapis.com/docs/ja/api-reference/uploads/images.md) first to upload images and get URLs, then call this endpoint.

## Routing Logic

The server automatically selects the upstream model based on what parameters you provide:

| パラメータ Provided | Upstream Mode |
| - | - |
| `metadata.reference_urls` (video URLs) | Reference Video (r2v) |
| `image_urls` (image) | Image-to-Video (i2v) |
| `prompt` only | Text-to-Video (t2v) |

## 認証

**Authorization** `string` *required*

All endpoints require Bearer Token authentication

Get your API Key from the [API Key Management Page](https://toapis.com/console/token)

Add to request header:

```
Authorization: Bearer YOUR_API_KEY
```

## リクエストパラメータ

**model** `string` *required*

Video generation model name, fixed as `wan2.6`

**prompt** `string` *required*

Video content description

必須 for text-to-video mode; optional for image-to-video and reference video modes (describe expected motion or style)

Example: `"A cute cat stretching in the sunshine"`

**image\_urls** `string[]`

Reference image URL array for image-to-video mode (only supports 1 image)

**⚠️ URL format only (base64 no longer supported)**

* Publicly accessible image URL (http\:// or https\://)
* You can use the [Upload 画像API](https://docs.toapis.com/docs/ja/api-reference/uploads/images.md) to upload local images and get URLs

Example: `["https://example.com/image.jpg"]`

**Note:** Cannot be combined with `metadata.reference_urls`

**aspect\_ratio** `string` (default: 16:9)

Video aspect ratio (applies to text-to-video and reference video modes)

Available values:

* `16:9` - Landscape (default)
* `9:16` - Portrait
* `1:1` - Square
* `4:3` - Landscape
* `3:4` - Portrait

Default: `16:9`

**Note:** Not supported in image-to-video mode

**resolution** `string` (default: 1080p)

Video resolution

Available values:

* `720p` - Standard definition
* `1080p` - High definition (default)

Default: `1080p`

480p is not supported. Billed per second; different resolutions have different prices — refer to the model marketplace for details.

**duration** `integer` (default: 5)

Video duration (seconds)

Supported values: `5`, `10`, `15`

Default: `5`

**negative\_prompt** `string`

Negative prompt — describe content you do not want in the video

Example: `"blurry, low quality, deformed"`

**seed** `integer`

Random seed for reproducibility

Example: `12345`

**prompt\_extend** `boolean` (default: true)

Auto-extend prompt

When enabled, the system automatically optimizes and enriches your prompt. **Enabled by default** — set to `false` to disable.

**audio** `boolean`

Include audio in the generated video

Non-flash Wan2.6 models always include audio by default. Set to `true` to explicitly enable.

**shot\_type** `string`

Shot type (applies to text-to-video and reference video modes)

Available values:

* `single` - Single continuous shot
* `multi` - Multi-shot (cinematic cuts)

**watermark** `boolean`

Add an Alibaba Cloud watermark to the generated video

**metadata** `object`

Extended parameters

**Show metadata fields**

**reference\_urls** `string[]`

**Reference Video (r2v) mode** — array of reference video URLs

When provided, the server routes to the reference video upstream model (wan2.6-r2v). The model uses these videos to guide generation of consistent characters or scenes.

* Each entry must be a publicly accessible video URL (http\:// or https\://)
* Up to several reference videos are supported

Example: `["https://cdn.example.com/ref1.mp4"]`

**Note:** Cannot be combined with `image_urls`

## Resolution and Aspect Ratio Combinations

| Aspect Ratio | 説明 | 720p Size | 1080p Size |
| - | - | - | - |
| 16:9 | Landscape (default) | 1280×720 | 1920×1080 |
| 9:16 | Portrait | 720×1280 | 1080×1920 |
| 1:1 | Square | 960×960 | 1440×1440 |
| 4:3 | Landscape | 1088×832 | 1632×1248 |
| 3:4 | Portrait | 832×1088 | 1248×1632 |

## レスポンス

Object type, always `generation.task`

**model** `string`

モデル name used

**status** `string`

Task status

> **Querying Task Results**
>
> Video generation is an asynchronous task. After submission, a `task_id` is returned. Use the [Get Video Task ステータス](https://docs.toapis.com/docs/ja/api-reference/tasks/video-status.md) interface to query generation progress and results.
