# youtube-full — YouTube Transcripts, Search, and Channel Data

Covers transcript extraction, video search, channel browsing, in-channel search, playlist extraction, and new-upload monitoring via TranscriptAPI.

> **Source:** Ported from [ZeroPointRepo/youtube-skills](https://github.com/ZeroPointRepo/youtube-skills) (MIT). Original skill authored by ZeroPointRepo contributors. Adapted for the claude-skills format.

> **BYOK / free-tier note:** TranscriptAPI is a commercial service (BYOK — you bring your own key; 100 free credits included, no card required). For local/self-hosted extraction without an API key, use `youtube-transcript-api` (Python) or `yt-dlp` as OSS fallbacks. See [Anti-Patterns](#anti-patterns) for guidance.

## API Setup

Every request to `transcriptapi.com` requires two headers:

- `Authorization: Bearer $TRANSCRIPT_API_KEY`
- `User-Agent: ClaudeCode/1.0`

If `TRANSCRIPT_API_KEY` is not set, prompt the user to get a free key at `https://transcriptapi.com` (100 free credits, no card required) and store it as `TRANSCRIPT_API_KEY`.

## Operations

### Get transcript (1 credit)

```
GET https://transcriptapi.com/api/v2/youtube/transcript
  ?video_url={URL_OR_ID}&format=text&include_timestamp=true&send_metadata=true
```

Use this for any "get transcript", "summarize video", or "extract quotes" request.

### Search YouTube (1 credit)

```
GET https://transcriptapi.com/api/v2/youtube/search
  ?q={QUERY}&type=video&limit=20
```

Use this when the user wants to find videos on a topic. Follow with transcript calls on selected results.

### Channel — latest uploads (FREE)

```
GET https://transcriptapi.com/api/v2/youtube/channel/latest
  ?channel={@HANDLE_OR_ID}
```

Returns the 15 most recent uploads with view counts and publish timestamps. Use before fetching transcripts to check whether uploads are new.

### Channel — all videos (1 credit/page)

```
GET https://transcriptapi.com/api/v2/youtube/channel/videos
  ?channel={@HANDLE_OR_ID}
```

Paginate with `?continuation=TOKEN` on subsequent pages.

### In-channel search (1 credit)

```
GET https://transcriptapi.com/api/v2/youtube/channel/search
  ?channel={@HANDLE_OR_ID}&q={QUERY}&limit=30
```

Prefer this over broad YouTube search when the user already knows the channel.

### Playlist extraction (1 credit/page)

```
GET https://transcriptapi.com/api/v2/youtube/playlist/videos
  ?playlist={PLAYLIST_URL_OR_ID}
```

Paginate with `?continuation=TOKEN`. Response includes `playlist_info`, `results`, `has_more`.

### Resolve handle (FREE)

```
GET https://transcriptapi.com/api/v2/youtube/channel/resolve
  ?input={@HANDLE_OR_URL}
```

Returns `{"channel_id": "UC...", "resolved_from": "@handle"}`.

## Common Workflows

### Research workflow

1. Search (`/search?q=...`) — pick the most relevant results
2. Fetch transcripts (`/transcript?video_url=...`) for selected videos
3. Summarize or extract quotes from transcript text

### Channel monitoring

1. `channel/latest` (free) — check for new uploads
2. If new videos found, fetch transcripts
3. Extract signal (announcement
