Authorizations

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 管理页面获取您的 API Key

使用时在请求头中添加：

Authorization: Bearer YOUR_API_KEY

Body

model string

图像生成模型名称

固定填写 imagen-4.0-openveer

prompt string

图像生成的文本描述

英文 / 中文描述均可

n integer

生成图片张数

取值范围：1

size string

图像生成的比例

支持的格式：

1:1 - 正方形
4:3 - 横屏
3:4 - 竖屏
16:9 - 横屏（默认）
9:16 - 竖屏

注意

传入不在支持列表里的比例（如 21:9）会被自动回退到默认 16:9，不会报错。

注意

不支持的字段：image、image_urls、mask、quality 等会被忽略。如果传入 image_urls / image 字段会直接报错：google_imagen4 currently supports text-to-image only。

Response

code integer

响应状态码

data array

返回数据数组

status string

任务状态

  * submitted - 已提交

task_id string

任务唯一标识符，用于后续查询任务结果
