# 将视频转视频调整大小与 Comfy Router 配合使用

> 通过 Comfy Router 调用 moonvalley/video-to-video-resize：端点、请求形状以及 Router 返回的响应。

`moonvalley/video-to-video-resize` 的 API 参考文档，由 Comfy Router 提供，来自 Moonvalley。

## 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 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 发出的同一调用。

**模型 ID：** `moonvalley/video-to-video-resize`

**端点：** `POST https://api.comfy.org/v2/models/moonvalley/video-to-video-resize`

## 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)。
