# 将 Eleven Sfx V2 与 Comfy Router 配合使用

> 通过 Comfy Router 调用 elevenlabs/eleven_sfx_v2：endpoint、请求结构以及 Router 返回的响应。

`elevenlabs/eleven_sfx_v2` 的 API 参考，由 Comfy Router 从 Elevenlabs 提供服务。

<h2 id="quick-start">
  快速开始
</h2>

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 代码片段使用 Comfy SDK（`pip install comfy-sdk`、`npm install @comfyorg/sdk`）；cURL 代码片段则通过原始 HTTP 发起相同的调用。

**模型 ID：** `elevenlabs/eleven_sfx_v2`

**端点：** `POST https://api.comfy.org/v2/models/elevenlabs/eleven_sfx_v2`

## 模式

### 输入

<ParamField body="duration_seconds" type="number" required>
  将要生成的声音的时长，单位为秒。
  必须至少为 0.5，最多为 30。
  此路由上为必填：与上游 ElevenLabs API 不同（当该字段为 null 时，
  上游会推测一个最佳时长），此路由会拒绝省略该字段的请求，
  并返回 400 "Duration is required"。
  该字段保持可为 null，只是为了让显式的 null 成为一个格式良好的
  文档；它仍然会被拒绝。
  该值是请求计量所依据的数量。

  范围：`0.5` 到 `30`

  格式：`double`
</ParamField>

<ParamField body="loop" type="boolean" default="false">
  是否创建可平滑循环的音效。
  ElevenLabs 的文档说明此选项仅适用于
  'eleven\_text\_to\_sound\_v2' 模型，而此路由不予接受该模型
  （见 model\_id），因此在这里它可能没有效果。
</ParamField>

<ParamField body="model_id" type="string">
  用于声音生成的模型 ID。此路由仅接受
  'eleven\_sfx\_v2'，其他任何值都会在请求到达 ElevenLabs 之前
  被拒绝并返回 400。它不在此模式的 `required` 列表中，
  因为 Comfy Router 会从 /v2/models/elevenlabs/\{model} 的
  `{model}` 路径段填充它，所以 Router
  调用方会省略它。
</ParamField>

<ParamField body="prompt_influence" type="number">
  提示词影响越高，生成结果就越贴近提示词，
  同时生成结果的多样性也会降低。
  必须是 0 到 1 之间的值。默认为 0.3。

  范围：`0` 到 `1`

  格式：`double`
</ParamField>

<ParamField body="text" type="string" required>
  将被转换为音效的文本。
</ParamField>

此内容根据 Router 在 `GET /v2/models/elevenlabs/eleven_sfx_v2/openapi.json` 提供的模式生成，该文档与它在请求到达提供商之前用于校验调用的文档相同。

### 输出

<ResponseField name="*/*" type="string (binary)">
  原始音频字节。Content-Type 和编码遵循所请求的 output\_format，并从 ElevenLabs 原样转发。示例是二进制主体的占位符，不是 JSON 或 base64。
</ResponseField>

### 输出

Router 不为此模型发布输出模式。

## 示例

### 输入

```json theme={null}
{
  "duration_seconds": 5,
  "text": "A distant rumble of thunder rolling across a valley."
}
```

## 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)。
