YouTube Playlist

Browse playlists and fetch transcripts 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.

API Reference

GET /api/v2/youtube/playlist/videos — 1 credit/page

Paginated playlist video listing (100 per page). Accepts `playlist` — a YouTube playlist URL or playlist ID.

# First page
GET https://transcriptapi.com/api/v2/youtube/playlist/videos?playlist=PL_PLAYLIST_ID
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0

# Next pages
GET https://transcriptapi.com/api/v2/youtube/playlist/videos?continuation=TOKEN

User-Agent: YourAgent/1.0

| Param | Required | Validation | | -------------- | ----------- | ---------------------------------------------------- | | `playlist` | conditional | Playlist URL or ID (`PL`/`UU`/`LL`/`FL`/`OL` prefix) | | `continuation` | conditional | non-empty string |

Provide exactly one of `playlist` or `continuation`, not both.

**Accepted playlist ID prefixes:**

• `PL` — user-created playlists
• `UU` — channel uploads playlist
• `LL` — liked videos
• `FL` — favorites
• `OL` — other system playlists

**Response:**

{
  "results": [
    {
      "videoId": "abc123xyz00",
      "title": "Playlist Video Title",
      "channelId": "UCuAXFkgsw1L7xaCfnd5JJOw",
      "channelTitle": "Channel Name",
      "channelHandle": "@handle",
      "lengthText": "10:05",
      "viewCountText": "1.5M views",
      "thumbnails": [{ "url": "...", "width": 120, "height": 90 }],
      "index": "0"
    }
  ],
  "playlist_info": {
    "title": "Best Science Talks",
    "numVideos": "47",
    "description": "Top science presentations",

    "viewCount": "5000000"
  },
  "continuation_token": "4qmFsgKlARIYVVV1...",
  "has_more": true
}

**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

# 1. List playlist videos
GET https://transcriptapi.com/api/v2/youtube/playlist/videos?playlist=PL_PLAYLIST_ID
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0

# 2. Get transcript from a video in the playlist
GET https://transcriptapi.com/api/v2/youtube/transcript?video_url=VIDEO_ID&format=text&include_timestamp=true&send_metadata=true
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0

Don't know a playlist ID? Find it from the channel

To browse a channel's playlists first (1 credit/page), then list videos in one of them:

# 1. List the channel's playlists
GET https://transcriptapi.com/api/v2/youtube/channel/playlists?channel=@TED
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0

# 2. List videos in the chosen playlist (playlistId from step 1)
GET https://transcriptapi.com/api/v2/youtube/playlist/videos?playlist=PLAYLIST_ID
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0

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.
