## What it does

The skill connects to the TranscriptAPI service to retrieve subtitles from YouTube videos. It accepts a video URL or video ID and returns the spoken text. You can request clean text for reading or structured JSON segments with start times and durations.

Requests require the `TRANSCRIPT_API_KEY` environment variable and an internet connection. Every request must include a custom `User-Agent` header with your agent name, because Cloudflare blocks requests without it with error 403.

This tool only reads existing captions and metadata like title or channel description. It cannot upload captions or manage YouTube accounts.

# Subtitles

Fetch YouTube video subtitles via [TranscriptAPI.com](https://transcriptapi.com).

## Setup

If `$TRANSCRIPT_API_KEY` is not set, read [references/auth-setup.md](references/auth-setup.md) and follow the instructions there to get and store the key.

## Required Headers

Every request needs two headers:

- **Authorization:** `Bearer $TRANSCRIPT_API_KEY`
- **User-Agent:** your agent's name and version if known (e.g. `HermesAgent/0.11.0`, `ClaudeCode/1.0`). Version is optional — agent name alone is fine. Do not omit this header or send a bare default — Cloudflare will return a 403 (error code 1010) and block the request.

## GET /api/v2/youtube/transcript

```bash
curl -s "https://transcriptapi.com/api/v2/youtube/transcript\
?video_url=VIDEO_URL&format=text&include_timestamp=false&send_metadata=true" \
  -H "Authorization: Bearer $TRANSCRIPT_API_KEY" \
  -H "User-Agent: YourAgent/1.0"
```

| Param               | Values                  | Use case                                       |
| ------------------- | ----------------------- | ---------------------------------------------- |
| `video_url`         | YouTube URL or video ID | Required                                       |
| `format`            | `json`, `text`          | `json` for sync'd subs with timing             |
| `include_timestamp` | `true`, `false`         | `false` for clean text for reading/translation |
| `send_metadata`     | `true`, `false`         | Include title, channel, description            |

**For language learning** — clean text without timestamps:

```bash
curl -s "https://transcriptapi.com/api/v2/youtube/transcript\
?video_url=VIDEO_ID&format=text&include_timestamp=false" \
  -H "Authorization: Bearer $TRANSCRIPT_API_KEY" \
  -H "User-Agent: YourAgent/1.0"
```

**For translation** — structured segments:

```bash
curl -s "https://transcriptapi.com/api/v2/youtube/transcript\
?video_url=VIDEO_ID&format=json&include_timestamp=true" \
  -H "Authorization: Bearer $TRANSCRIPT_API_KEY" \
  -H "User-Agent: YourAgent/1.0"
```

**Response** (`format=json`):

```json
