# YouTube Transcripts

Collect one plain-text transcript for each public video URL.

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

## Use with MCP

| Interface      | Value                                                 |
| -------------- | ----------------------------------------------------- |
| REST           | `POST /v1/youtube/transcripts`                        |
| Compact MCP    | `socq_execute` with `endpoint: "youtube/transcripts"` |
| Typed MCP      | `socq_youtube_transcripts`                            |
| Exact-tool URL | `https://api.socq.ai/mcp?tools=youtube_transcripts`   |
| CLI            | `socq youtube transcripts`                            |

Use the JSON request body above as the nested `input` object for `socq_execute`, or pass the same fields directly to the typed tool. Typed tools also accept `_wait_seconds`, `_result_limit`, and `_idempotency_key`.

<Info>
  A successful collection returns a `task_id`. Continue with `socq_get_task` until the task succeeds, then read normalized records from `results.items`.
</Info>

See [MCP quickstart](/integrations/mcp) for the complete submission and polling flow.

`language` is an optional BCP-47 preferred language. If it is unavailable, another available language may be returned. Always use the result's `language` field as the actual transcript language.

Videos without an available transcript do not produce a result.
