认证

Authorization string

所有接口均需要使用 Bearer Token 进行认证获取 API Key：访问 [API Key 管理页面](https://openveer.com) 获取您的 API Key 使用时在请求头中添加： ``` Authorization: Bearer YOUR_API_KEY ```

请求参数

model string

视频生成模型名称，固定为 `wan2.5-preview`

prompt string

视频内容描述文生视频（无 `image_urls`）时**必填**，图生视频时可选但建议填写建议详细描述场景、动作、风格等示例：`"夕阳下的海边公路，电影感镜头"`

image_urls string

"> 参考图片 URL 数组（仅支持 1 张首帧图片）图生视频模式下必填，支持公网可访问的图片 URL 或 Base64 编码（`data:image/png;base64,...`）示例：`["https://example.com/image.jpg"]`

注意

系统会根据请求中是否包含 `image_urls` 自动选择文生视频或图生视频模式。文生模式**不要**传 `image_urls`。

negative_prompt string

反向提示词，描述不希望出现的内容最多 500 字符示例：`"模糊, 低质量, 变形"`

resolution string

视频分辨率可选值： * `480p` - 标清，支持 size：`16:9`、`9:16`、`1:1` * `720p` - 高清（默认），支持 size：`16:9`、`9:16`、`1:1`、`4:3`、`3:4` * `1080p` - 超清，支持 size：`16:9`、`9:16`、`1:1`、`4:3`、`3:4` 默认值：`720p`

注意

分辨率直接影响费用，1080p > 720p > 480p。

警告

480p 仅支持 `16:9`、`9:16`、`1:1` 三种比例，传 `4:3` 或 `3:4` 会报错

duration integer

视频时长（秒）仅支持：`5` 或 `10` 秒默认值：`5`

size string

画面宽高比，**仅文生视频**（无 `image_urls`）有效可选值取决于 `resolution`： **480p：** * `16:9` - 横屏（默认） * `9:16` - 竖屏 * `1:1` - 方形 **720p / 1080p：** * `16:9` - 横屏（默认） * `9:16` - 竖屏 * `1:1` - 方形 * `4:3` - 横屏 * `3:4` - 竖屏默认值：`16:9`

警告

图生视频的宽高比由输入图片决定，**不要**传 `size`，否则会报错

seed integer

随机种子（≥0），指定相同种子可复现相似结果示例：`12345`

prompt_extend boolean

是否开启 prompt 智能改写对较短提示词效果提升明显，但会增加耗时默认值：`true`

audio boolean

是否自动添加音频启用后系统会为视频自动生成匹配的音频默认值：`true`

警告

该模型仅支持 `audio=true`，不支持设为 `false` 生成无声视频

audio_url string

自定义音频 URL（wav/mp3，3-30 秒，≤ 15MB）若音频长度超过视频时长，自动截取；不足则超出部分为无声

警告

音频文件要求： * 格式：wav、mp3 * 时长：3-30 秒 * 大小：≤ 15MB

watermark boolean

是否添加 "AI生成" 水印（右下角）默认值：`false`

分辨率与宽高比组合

size 与 resolution 组合映射为上游像素尺寸（仅文生视频有效）：

宽高比	说明	480p 尺寸	720p 尺寸	1080p 尺寸
`16:9`	横屏（默认）	832×480	1280×720	1920×1080
`9:16`	竖屏	480×832	720×1280	1080×1920
`1:1`	方形	624×624	960×960	1440×1440
`4:3`	横屏	-	1088×832	1632×1248
`3:4`	竖屏	-	832×1088	1248×1632

注意

480p 仅支持 `16:9`、`9:16`、`1:1` 三种比例，传 `4:3` 或 `3:4` 会报错。720p 和 1080p 支持全部 5 种比例。

响应

code integer

响应状态码，成功时为 200

data array

返回数据数组任务状态，初始提交时为 `submitted`

task_id string

任务唯一标识符，用于查询任务状态和结果

模式说明

文生视频 (Text-to-Video)

必须提供 prompt 参数
不需要 image_urls 参数
可通过 size 指定画面宽高比

图生视频 (Image-to-Video)

必须提供 image_urls 参数（仅支持 1 张图片）
prompt 参数可选，用于描述期望的动作
宽高比由输入图片决定，不要传 size

注意

系统会根据请求中是否包含 `image_urls` 自动选择模式

注意

**查询任务结果** 视频生成为异步任务，提交后会返回 `task_id`。使用 [获取任务状态](/cn/api-reference/tasks/status) 接口查询生成进度和结果。
