# Video Transcript
Extract transcripts from videos 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=true&send_metadata=true" \
-H "Authorization: Bearer $TRANSCRIPT_API_KEY" \
-H "User-Agent: YourAgent/1.0"
```

## Tips
- Summarize long transcripts into key points first, offer full text on request.
- Use `format=json` when you need precise timestamps for quoting specific moments.
- Use `send_metadata=true` to get video title and channel for context.
- Works with YouTube Shorts too.
