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

视频生成模型名称支持的模型： * `kling-3.0-turbo` - 可灵 3.0 Turbo

prompt string

文本提示词上游限制不超过 3072 字符，建议不超过 2500 字符。示例：`"一只柯基在海边奔跑，电影感，黄昏光线"`

first_frame_image string

支持 **图片 URL** 或 **Base64**。

警告

首帧图上游限制： * 格式：`.jpg` / `.jpeg` / `.png` * 大小：≤ 50MB * 宽高：≥ 300px * 宽高比：`1:2.5` \~ `2.5:1`

aspect_ratio string

视频宽高比可选值： * `16:9` - 横屏 * `9:16` - 竖屏 * `1:1` - 方形默认值：`16:9`

注意

**仅文生视频生效**。图生视频时此字段无效，视频比例由首帧图决定。

resolution string

视频清晰度可选值： * `720p` * `1080p` 默认值：`720p`

duration integer

视频时长（秒）取值范围：3-15（最短 3 秒，最长 15 秒）默认值：`5` **⚠️ 注意：** 必须输入纯数字（如 `6`），不要加引号，否则会报错

watermark boolean

是否添加水印仅当显式传入时才下发到上游；不传则不添加水印。

文生视频 vs 图生视频

系统会根据是否提供 first_frame_image 自动判断生成模式：有首帧图走图生视频，无首帧图走文生视频，用户无需显式声明。

参数	文生视频	图生视频
`prompt`	✅ 必填	✅ 可选（留空纯按首帧图生成）
`first_frame_image`	❌ 不传	✅ 必填
`aspect_ratio`	✅ 可选	❌ 无效（比例由首帧图决定）
`resolution`	✅ 可选	✅ 可选
`duration`	✅ 可选（3-15）	✅ 可选（3-15）
`watermark`	✅ 可选	✅ 可选

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

使用场景

场景 1：文生视频（1080P）

{
  "model": "kling-3.0-turbo",
  "prompt": "一只柯基在海边奔跑，电影感，黄昏光线",
  "aspect_ratio": "16:9",
  "resolution": "1080p",
  "duration": 5
}

场景 2：文生视频（竖屏 720P）

{
  "model": "kling-3.0-turbo",
  "prompt": "东京涩谷十字路口，雨夜霓虹灯倒映在湿漉漉的地面上，行人撑伞穿行",
  "aspect_ratio": "9:16",
  "resolution": "720p",
  "duration": 10
}

场景 3：图生视频（首帧图片）

{
  "model": "kling-3.0-turbo",
  "prompt": "镜头缓慢推近，人物微笑",
  "first_frame_image": "https://cdn.example.com/first.jpg",
  "resolution": "720p",
  "duration": 5
}

场景 4：纯首帧图生视频（不带提示词）

{
  "model": "kling-3.0-turbo",
  "first_frame_image": "https://cdn.example.com/first.jpg",
  "resolution": "1080p",
  "duration": 5
}

场景 5：多镜头分镜（文生视频）

{
  "model": "kling-3.0-turbo",
  "prompt": "镜头 1,2,海边柯基奔跑；镜头 2,3,镜头推近人物微笑；",
  "aspect_ratio": "16:9",
  "resolution": "1080p",
  "duration": 5
}

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。
