Video Transcript

Extract transcripts from videos via TranscriptAPI.com.

Setup

If $TRANSCRIPT_API_KEY is not set, read 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.

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.
