生产建议

  • 显式传入 mode。
  • 只使用上表列出的参数值。
  • 媒体输入类 mode 请先用 POST /api/v1/files 上传素材。
  • 如果页面包含多个变体，请使用你真正需要的模型 key。

示例：文生图

curl https://img2vid.net/api/v1/generations \
  -H "Authorization: Bearer $BUBLE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "google/nano-banana-pro",
    "mode": "text_to_image",
    "prompt": "A premium editorial product image of a minimalist ceramic coffee grinder on a warm walnut counter, soft studio lighting",
    "aspect_ratio": "1:1",
    "resolution": "1K",
    "output_format": "png"
  }'

示例：图生图

Upload an image first, then pass the returned URL to image_urls.

curl https://img2vid.net/api/v1/generations \
  -H "Authorization: Bearer $BUBLE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "google/nano-banana-pro",
    "mode": "image_to_image",
    "prompt": "Transform the source into a clean commercial product image while preserving the main object",
    "image_urls": ["https://example.com/source.png"],
    "aspect_ratio": "1:1",
    "resolution": "1K",
    "output_format": "png"
  }'

SDK 示例

下面的示例使用本页的公开模型 key、mode 和参数值。片段假设你已经按快速开始初始化了 SDK client，并引入了对应语言需要的 SDK 类型。媒体输入类 mode 仍然需要先上传本地文件，再把返回的 URL 放入 image_urls、start_frame、video_urls 等公开字段。
