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.

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

Tips
- For long videos, summarize key points first, offer full transcript on request.
- Use
format=jsonwhen you need precise timestamps for quoting specific moments. - Use
include_timestamp=falsefor clean text suitable for translation or analysis. - 1 credit per successful request. Errors don't cost credits.
- Free tier: 100 credits, 300 req/min.
