本文介紹 Nano Banana Images API 的對接與使用。該接口支持兩種能力:圖像生成(generate)圖像編輯(edit)

申請流程

使用前,請在 Ace Data Cloud 平台中進入 Nano Banana Images API 並點擊 Acquire 申請開通。首次申請通常會有免費額度可用。開通完成後,即可在平台中獲取到用於調用 API 的 Bearer Token。

  • EndpointPOST /nano-banana/images
  • 認證方式:HTTP Header 中攜帶 authorization: Bearer {token}
  • 請求頭
    • accept: application/json
    • content-type: application/json
  • 動作(action)
    • generate:根據文本提示詞生成圖片
    • edit:基於給定圖片進行編輯

快速開始:生成圖片(action=generate

最小必需參數actionprompt 當你只想根據提示詞直接出圖時,設置 actiongenerate,並提供清晰的 prompt 即可。

請求示例(cURL)

curl -X POST 'https://api.acedata.cloud/nano-banana/images' \
  -H 'authorization: Bearer {token}' \
  -H 'accept: application/json' \
  -H 'content-type: application/json' \
  -d '{
    "action": "generate",
    "prompt": "A photorealistic close-up portrait of an elderly Japanese ceramicist with deep, sun-etched wrinkles and a warm, knowing smile. He is carefully inspecting a freshly glazed tea bowl. The setting is his rustic, sun-drenched workshop. The scene is illuminated by soft, golden hour light streaming through a window, highlighting the fine texture of the clay. Captured with an 85mm portrait lens, resulting in a soft, blurred background (bokeh). The overall mood is serene and masterful. Vertical portrait orientation.",

字段說明

  • success:本次請求是否成功。
  • task_id:任務 ID。
  • trace_id:鏈路追蹤 ID,便於排查問題。
  • data[]:結果列表。
    • prompt:用於生成的提示詞(回顯)。
    • image_url:生成圖片的直鏈 URL。
注:/nano-banana/images 僅需 actionprompt 即可生成圖片

編輯圖片(action=edit

當你希望基於已有圖片進行編輯時,設置 actionedit,並通過 image_urls 傳入待編輯的圖片鏈接列表(1 張或多張),同時提供描述編輯目標的 prompt 比如這裡我們提供一張人物照片,一張衣服照片,讓人物穿上這個衣服,就可以同時傳入圖片鏈接,並且指定 action 為 edit,URL 可以是 HTTP URL,以 httpshttp 協議的公開可訪問鏈接,也可以是 Base64 編碼的圖片,如 data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAA+gAAAVGCAMAAAA6u2FyAAADAFBMVEXq6uwdHCEeHyMdHS....

  ]
}

字段說明

  • image_urls[]:待編輯圖片 URL 列表(必須可公網訪問)。可傳多張,服務會結合這些素材與 prompt 完成編輯。
  • 其餘字段同「生成圖片」返回。

異步回調(可選,推薦)

生成或編輯可能需要一定時間。為避免長連接佔用資源,建議通過 callback_url 使用 Webhook 回調
  1. 在請求體中添加 callback_url,例如你的服務端 Webhook 地址(需可公網訪問,支持 POST JSON)。
  2. API 會 立即返回 包含 task_id 的響應(或包含基本結果)。
  3. 當任務完成後,平台將以 POST 的方式將完整 JSON 發送至 callback_url。你可以通過 task_id 將請求與結果關聯。
回調載荷示例(字段結構與同步成功返回一致):
{
  "success": true,
  "task_id": "6a97bf49-df50-4129-9e46-119aa9fca73c",
  "trace_id": "9b4b1ff3-90f2-470f-b082-1061ec2948cc",
  "data": [
    {
      "prompt": "a white siamese cat",
      "image_url": "https://platform.cdn.acedata.cloud/nanobanana/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.png"
    }
  ]
}

錯誤處理

調用失敗時會返回標準錯誤格式與追蹤 ID。常見錯誤如下:
  • 400 token_mismatched:請求不合法或參數錯誤。
  • 400 api_not_implemented:接口未實現(請聯繫支持)。
  • 401 invalid_token:鑑權失敗或缺少 Token。
  • 429 too_many_requests:請求頻率超限。
  • 500 api_error:服務端異常。

錯誤響應示例

{
  "success": false,
  "error": {
    "code": "api_error",
    "message": "Internal server error."
  },
  "trace_id": "2cf86e86-22a4-46e1-ac2f-032c0f2a4e89"
}

參數對照與注意事項

  • 必填actionprompt
  • 編輯專用image_urls(數組,至少 1 項)
  • 可選model(默認 nano-banana,可選 nano-banana-2nano-banana-pro)、aspect_ratio(寬高比,如 1:116:9)、resolution(分辨率,如 1K2K4K)、callback_url(用於異步回調)
  • Headers:必須提供 authorization: Bearer {token}accept 建議設為 application/json
  • 圖片可訪問性image_urls 必須為可公網訪問的直鏈(HTTP/HTTPS),建議使用 HTTPS
  • 幂等與追蹤:保留 task_idtrace_id,便於故障排查與結果關聯
