Nano Banana Pro API

Use Nano Banana Pro through Xenodia with resolution tiers, aspect ratio, output format, reference input, and task mode.

nano-banana-pro 使用 shared image endpoint：

POST https://api.xenodia.xyz/v1/images/generations

当你需要显式控制 aspect ratio、resolution、output format 和 reference images 时使用这页。

Request

{
  "model": "nano-banana-pro",
  "prompt": "A clean studio render of a developer API dashboard on a glass desk.",
  "aspect_ratio": "16:9",
  "resolution": "2K",
  "output_format": "png",
  "response_format": "url"
}

Task request

  "prompt": "Create a polished product hero image for Xenodia docs.",
  "aspect_ratio": "16:9",

}

返回 task 后通过 Task Retrieval 轮询。
