# 将 Krea 2 Medium Turbo 与 Comfy Router 搭配使用

> 通过 Comfy Router 调用 krea/krea-2-medium-turbo：端点、请求结构以及 Router 返回的响应。

`krea/krea-2-medium-turbo` 的 API 参考，该模型由 Comfy Router 提供，来源为 Krea。

## 快速开始

在[你的 Comfy 工作区](https://platform.comfy.org/profile/api-keys)中创建一个密钥，并将其导出为 `COMFY_API_KEY`。Python 和 TypeScript 代码片段使用 Comfy SDK（`pip install comfy-sdk`、`npm install @comfyorg/sdk`）；cURL 代码片段则是通过原始 HTTP 发起的同一个调用。

**模型 ID：** `krea/krea-2-medium-turbo`

**端点：** `POST https://api.comfy.org/v2/models/krea/krea-2-medium-turbo`

  用于生成的情绪板（moodboard）。目前限制为一个情绪板。
</ParamField>

<ParamField body="moodboards[].id" type="string (uuid)" required>
  格式：`uuid`
</ParamField>

<ParamField body="moodboards[].strength" type="number" default="0.35">

由 Router 在 `GET /v2/models/krea/krea-2-medium-turbo/openapi.json` 提供的 schema 生成，它与请求到达提供商之前用于校验调用的文档是同一份。

### Output

<ResponseField name="completed_at" type="string (date-time)" required>
  格式：`date-time`
</ResponseField>

<ResponseField name="created_at" type="string (date-time)" required>

  格式：`uuid`
</ResponseField>

<ResponseField name="result" type="object" required>
  已完成的生成。与 `KreaJob` 上不同，此处不可为空：`result` 中不包含 `urls` 的终端任务会以 Comfy Router 错误作为响应，因此 `200` 响应中总会带有该字段。
</ResponseField>

<ResponseField name="result.style_id" type="string">
  由 loraTraining 任务设置，而非由生成设置；这些模型的 `200` 响应带有 `urls`。
</ResponseField>

<ResponseField name="result.urls" type="string (uri)[]" required>
  已生成的图像，以可下载链接的形式提供。至少有一个，因为 `urls` 为空的 `completed` 任务属于 `success_without_output`，永远不会出现在此文档中。
</ResponseField>

<ResponseField name="status" type="string" required>
  在此文档中始终为 `completed`：它是 `classifyKrea` 判定为 `succeeded` 的唯一状态，并且匹配 Krea 的词汇时不进行大小写折叠。

  Possible values: `completed`
</ResponseField>

## 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)。
