Youtube Playlist

YouTube Playlist

Browse playlists and fetch transcripts via 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.

  "results": [
    {
      "videoId": "abc123xyz00",
      "title": "Playlist Video Title",
      "channelId": "UCuAXFkgsw1L7xaCfnd5JJOw",

Pagination flow:

1. First request: ?playlist=PLxxx — returns first 100 videos + continuation_token
2. Next request: ?continuation=TOKEN — returns next 100 + new token
3. Repeat until has_more: false or continuation_token: null

Workflow: Playlist → Transcripts

# 2. Get transcript from a video in the playlist

Extract playlist ID from URL

From https://www.youtube.com/playlist?list=PLrAXtmErZgOeiKm4sgNOknGvNjby9efdf, the playlist ID is PLrAXtmErZgOeiKm4sgNOknGvNjby9efdf. You can also pass the full URL directly to the playlist parameter.
