> 从公开 YouTube 视频中采集纯文本视频字幕。

# YouTube 视频字幕

为每个公共视频 URL 采集一份纯文本视频字幕。

```json theme={"system"}
{
  "urls": ["https://www.youtube.com/watch?v=VIDEO_ID"],
  "language": "en"
}
```

## 与 MCP 一起使用

| 接口          | 值                                                   |
| ----------- | --------------------------------------------------- |
| REST        | `POST /v1/youtube/transcripts`                      |
| Compact MCP | `socq_execute` 与 `endpoint: "youtube/transcripts"`  |
| Typed MCP   | `socq_youtube_transcripts`                          |
| 精确工具 URL    | `https://api.socq.ai/mcp?tools=youtube_transcripts` |
| CLI         | `socq youtube transcripts`                          |

使用上面的 JSON 请求正文作为 `socq_execute` 的嵌套 `input` 对象，或将相同的字段直接传递给Typed 工具。Typed 工具还接受 `_wait_seconds`、`_result_limit` 和 `_idempotency_key`。

<Info>
  成功的采集将返回 `task_id`。继续 `socq_get_task` 直到任务成功，然后从 `results.items` 读取规范化记录。
</Info>

有关完整的提交和轮询流程，请参阅[MCP 快速入门](/zh/integrations/mcp)。

`language` 是可选的 BCP-47 首选语言。如果不可用，则可能会返回另一种可用语言。始终使用结果的 `language` 字段作为实际的转录语言。

没有可用视频字幕的视频不会产生结果。
