本文介绍 Nano Banana Images API 的对接与使用。该接口支持两种能力：图像生成（generate） 与 图像编辑（edits）。

申请流程

使用前，请在 Ace Data Cloud 平台中进入 Nano Banana Images API 并点击 Acquire 申请开通。首次申请通常会有免费额度可用。开通完成后，即可在平台中获取到用于调用 API 的 Bearer Token。

接口概览

• Base URL：https://api.acedata.cloud
• Endpoint：POST /nano-banana/images
• 认证方式：HTTP Header 中携带 authorization: Bearer {token}

• 请求头：

• accept: application/json

• content-type: application/json

• 动作（action）：

• generate：根据文本提示词生成图片

• edits：基于给定图片进行编辑

• 异步回调：可选，通过 callback_url 接收任务完成通知与结果

快速开始：生成图片（action=generate）

最小必需参数：action、prompt 当你只想根据提示词直接出图时，设置 action 为 generate，并提供清晰的 prompt 即可。

请求示例（cURL）

bash 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." }'

请求示例（Python）

```python import requests

url = "https://api.acedata.cloud/nano-banana/images" headers = { "authorization": "Bearer {token}", "accept": "application/json", "content-type": "application/json", } payload = { "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." ), } resp = requests.post(url, json=payload, headers=headers) print(resp.json()) ```

成功返回示例

json { "success": true, "task_id": "056f0589-a3dd-4ec2-8440-ad61f5038dfa", "trace_id": "c48de83f-0077-426e-b02b-ff1d58179064", "data": [ { "prompt": "A photorealistic close-up portrait of an elderly Japanese ceramicist with deep, sun-etched wrinkles and a warm, knowing smile.

字段说明

• success：本次请求是否成功。
• task_id：任务 ID。
• trace_id：链路追踪 ID，便于排查问题。

• data[]：结果列表。

• prompt：用于生成的提示词（回显）。

• image_url：生成图片的直链 URL。

注：/nano-banana/images 仅需 action 与 prompt 即可生成图片

编辑图片（action=edit）

当你希望基于已有图片进行编辑时，设置 action 为 edit，并通过 image_urls 传入待编辑的图片链接列表（1 张或多张），同时提供描述编辑目标的 prompt。

比如这里我们提供一张人物照片，一张衣服照片，让任务穿上这个衣服，就可以同时传入图片链接，并且指定 action 为 edit，URL 可以是 HTTP URL，以 https 或 http 协议的公开可访问链接，也可以是 Base64 编码的图片，如 data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAA+gAAAVGCAMAAAA6u2FyAAADAFBMVEXq6uwdHCEeHyMdHS....

请求示例（cURL）

bash 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": "edit", "prompt": "let this man wear on this T-shirt", "image_urls": [ "https://cdn.acedata.cloud/v8073y.png", "https://cdn.acedata.cloud/44xlah.png" ] }'

请求示例（Python）

```python import requests

url = "https://api.acedata.cloud/nano-banana/images" headers = { "authorization": "Bearer {token}", "accept": "application/json", "content-type": "application/json", } payload = { "action": "edit", "prompt": "let this man wear on this T-shirt", "image_urls": [ "https://cdn.acedata.cloud/v8073y.png", "https://cdn.acedata.cloud/44xlah.png" ] } resp = requests.post(url, json=payload, headers=headers) print(resp.json()) ```

成功返回示例

json { "success": true, "task_id": "93f11baf-347b-4bb4-9520-8653cb46d6a3", "trace_id": "a9063166-26ed-4451-85b5-54e896817c69", "data": [ { "prompt": "let this man wear on this T-shirt", "image_url": "https://platform.cdn.acedata.cloud/nanobanana/8e9e0253-26f4-45b9-b3f8-ac1aed1c284b.png" } ] }

字段说明

• image_urls[]：待编辑图片 URL 列表（必须可公网访问）。可传多张，服务会结合这些素材与 prompt 完成编辑。
• 其余字段同「生成图片」返回。

---

异步回调（可选，推荐）

生成或编辑可能需要一定时间。为避免长连接占用资源，建议通过 callback_url 使用 Webhook 回调：

1. 在请求体中添加 callback_url，例如你的服务端 Webhook 地址（需可公网访问，支持 POST JSON）。
2. API 会 立即返回 包含 task_id 的响应（或包含基本结果）。
3. 当任务完成后，平台将以 POST 的方式将完整 JSON 发送至 callback_url。你可以通过 task_id 将请求与结果关联。

回调载荷示例（字段结构与同步成功返回一致）：

json { "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" } ] }

错误处理

调用失败时会返回标准错误格式与追踪 ID。常见错误如下：

• 400 token_mismatched：请求不合法或参数错误。
• 400 api_not_implemented：接口未实现（请联系支持）。
• 401 invalid_token：鉴权失败或缺少 Token。
• 429 too_many_requests：请求频率超限。
• 500 api_error：服务端异常。

错误响应示例

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