信息

**模型名兼容提示**：本接口同时兼容别名 `veo3.1-fast-ext`（等价于 `veo3.1-fast`）、`veo3.1-quality-ext`（等价于 `veo3.1-quality`）、`veo3.1-lite-ext`（等价于 `veo3.1-lite`），别名与主名可互换使用、效果一致。

请求示例

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

视频生成模型名称可用模型： * `veo3.1-fast` - 快速生成模型，适用于快速预览和迭代（兼容别名 `veo3.1-fast-ext`） * `veo3.1-quality` - 高质量生成模型，适用于最终制作（兼容别名 `veo3.1-quality-ext`） * `veo3.1-lite` - 轻量级生成模型，适用于低成本批量生成（兼容别名 `veo3.1-lite-ext`） Example: `"veo3.1-fast"`

注意

为兼容旧版调用，别名 `veo3.1-fast-ext`（对应 `veo3.1-fast`）、`veo3.1-quality-ext`（对应 `veo3.1-quality`）、`veo3.1-lite-ext`（对应 `veo3.1-lite`）仍可正常使用。

prompt string

视频生成的文本描述

duration integer

视频时长（秒）固定值：`8`（VEO3 仅支持 8 秒时长）

aspect_ratio string

视频宽高比支持的格式： * `16:9` (横屏) * `9:16` (竖屏)

generation_type string

视频生成类型支持的类型： * `frame` - 帧转视频（FL模式） * `reference` - 参考图生视频如果不传此参数，默认根据图片数量自动判断：2张为帧转视频，3张为参考图生视频 **注意：`veo3.1-quality` 模型不支持 `reference` 参考图模式**

警告

`veo3.1-lite` 模型不支持此参数，请勿传入

image_urls string

"> 用于图生视频的参考图像 URL 数组支持公网可访问的图片 URL（http\:// 或 https\://）示例：`["https://example.com/image.jpg"]` **限制：** * 最多 3 张图片 * 帧转视频模式：第一张为首帧，第二张为尾帧 * 最大文件大小：10MB * 支持格式：.jpeg、.jpg、.png、.webp

警告

`veo3.1-lite` 模型不支持此参数，请勿传入

resolution string

视频分辨率支持的值： * `720p`（默认） * `1080p` * `4k`

enable_gif boolean

启用 GIF 输出格式。默认：false 注意：GIF 和 1080p、4k 分辨率不能同时使用

official_fallback boolean

是否使用官方渠道兜底 * `false`：不使用（默认） * `true`：使用官方渠道

警告

`veo3.1-lite` 模型不支持此参数，请勿传入

Response

code integer

响应状态码

data array

返回数据数组任务状态 * `submitted` - 已提交

task_id string
