# 搭配 Comfy Router 使用 Qwen Image 3.0 Pro

> 通过 Comfy Router 调用 qwen/qwen-image-3.0-pro：端点、请求格式以及 Router 返回的响应。

`qwen/qwen-image-3.0-pro` 的 API 参考文档，由 Comfy Router 从 Qwen 提供服务。

## 快速开始

在[你的 Comfy 工作区](https://platform.comfy.org/profile/api-keys)中创建密钥，并将其导出为 `COMFY_API_KEY`。Python 和 TypeScript 片段使用 Comfy SDK（`pip install comfy-sdk`、`npm install @comfyorg/sdk`）；cURL 片段是通过原始 HTTP 发起的同一调用。

**模型 ID：** `qwen/qwen-image-3.0-pro`

**端点：** `POST https://api.comfy.org/v2/models/qwen/qwen-image-3.0-pro`

  请求内容数组。仅支持单轮对话，因此该数组必须恰好包含一个对象
</ParamField>

<ParamField body="input.messages[].content" type="object[]" required>
  消息内容数组。文生图包含一个 text 对象；图像编辑包含 1-3 个 image 对象和一个 text 对象
</ParamField>

<ParamField body="input.messages[].content[].image" type="string">
  输入图像的 URL 或 Base64 编码数据。图像编辑支持 1-3 张图像

<ParamField body="model" type="string">
  用于多模态图像生成与编辑的模型 ID。可选值为 qwen-image-3.0-pro 和 qwen-image-3.0。它不在本 schema 的 `required` 列表中，因为 Comfy Router 会从 /v2/models/qwen/\{model} 的 `{model}` 路径段中填充它，所以 Router 调用方会省略该字段；而直接以 v1 调用 /proxy/ 路由时必须提供它。
</ParamField>

<ParamField body="parameters" type="object">

</ParamField>

<ParamField body="parameters.n" type="integer" default="1">
  输出图像的数量。范围为 1-6，默认为 1

  范围：`1` 到 `6`
</ParamField>

<ParamField body="parameters.negative_prompt" type="string">
  描述你不希望出现在图像中的内容的负面提示词
</ParamField>

<ParamField body="parameters.prompt_extend" type="boolean" default="true">
  是否启用提示词智能改写。默认为 true
</ParamField>

<ParamField body="parameters.prompt_extend_mode" type="string" default="&#x22;direct&#x22;">
  提示词改写方法，direct（默认，支持 T2I 和 I2I）或 agent（仅支持 T2I）

  可选值：`direct`、`agent`
</ParamField>

<ParamField body="parameters.seed" type="integer">
  用于控制随机性的随机数种子。范围 \[0, 2147483647]

  范围：`0` 到 `2147483647`
</ParamField>

<ParamField body="parameters.size" type="string">
  输出图像分辨率，格式为 宽*高，例如 1024*1024。API 接受的像素面积介于 262144 (512*512) 与 6553600 (2560*2560) 之间，宽高比介于 1:8 与 8:1 之间。若未指定，模型会根据提示词自动推荐分辨率
</ParamField>

<ParamField body="parameters.watermark" type="boolean" default="false">
  是否添加水印。默认为 false
</ParamField>

本文档根据 Router 在 `GET /v2/models/qwen/qwen-image-3.0-pro/openapi.json` 提供的 schema 生成，该 schema 也是请求到达提供商之前 Router 校验调用时所依据的同一份文档。

</ResponseField>

<ResponseField name="message" type="string">

  已生成图像的 URL，格式为 PNG。该链接有效期为 24 小时
</ResponseField>

<ResponseField name="output.choices[].message.content[].text" type="string">
  代替图像返回的文本元素。仅带有此字段的元素不会产出任何资源，因此调用方应依据 `image` 而非内容元素是否存在来判断是否完成
</ResponseField>

<ResponseField name="output.choices[].message.role" type="string">
  消息的角色。固定为 assistant
</ResponseField>

<ResponseField name="request_id" type="string">
  唯一请求标识符

## 发布前须知

SDK 会生成 `Idempotency-Key` 并在自动重试中复用它。手动重试时，请复用原始 key。Router 最长可保持连接 10 分钟。

请求失败时，Router 会发送 `X-Comfy-Error-Type` 响应头说明原因。`422` 表示 Router 在调用提供商之前就拒绝了输入。生成的资源请及时下载，因为[结果链接会过期](/zh/development/comfy-router/reference#结果资产)。
