# 将 Claude Fable 5.1 与 Comfy Router 配合使用

> 通过 Comfy Router 调用 anthropic/claude-fable-5-1：endpoint、请求结构以及 Router 返回的响应。

`anthropic/claude-fable-5-1` 的 API 参考文档，由 Comfy Router 从 Anthropic 提供。

## 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 代码片段是通过原始 HTTP 发起的相同调用。

**模型 ID：** `anthropic/claude-fable-5-1`

**端点：** `POST https://api.comfy.org/v2/models/anthropic/claude-fable-5-1`

  对话轮次。完整的内容块分类请参阅 Anthropic Messages API 文档。
</ParamField>

<ParamField body="messages[].content" type="object" required>
  可以是字符串简写，也可以是内容块数组（text、image、document、tool\_use、tool\_result……）。
</ParamField>

<ParamField body="messages[].role" type="string" required>
  可能的值：`user`、`assistant`
</ParamField>

<ParamField body="model" type="string">

  "content": [
    {
      "text": "ok",
      "type": "text"
    }
  ],
  "id": "msg_01ExampleInvalidPlaceholder",

    "input_tokens": 16,
    "output_tokens": 3
  }
}
```

## 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)。
