youtube-api
Use when YouTube data is needed without Google API quotas or OAuth setup: transcripts, video metadata, channel info, search results, playlists. Triggers on pasted YouTube links, creator names, @handles, topic research, video summaries, channel browsing, or any request where YouTube content would help — even if not mentioned explicitly. Not for uploads, account management, or written-source-only research.

Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/zeropointrepo/youtube-skills --skill youtube-api- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads youtube-api automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
YouTube API
YouTube data access via TranscriptAPI.com — no Google API quota needed.
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.
API Reference
Full OpenAPI spec: transcriptapi.com/openapi.json — consult this for the latest parameters and schemas.
Endpoint Reference
All endpoints: https://transcriptapi.com/api/v2/youtube/...
Channel endpoints accept channel — an @handle, channel URL, or UC... ID. Playlist endpoints accept playlist — a playlist URL or ID.
| Endpoint | Method | Cost |
|---|---|---|
/info?video_url=ID | GET | free |
/video/metadata?video_url=ID | GET | 1 |
/transcript?video_url=ID | GET | 1 |
/search?q=QUERY&type=video | GET | 1 |
/channel/resolve?input=@handle | GET | free |
/channel/info?channel=@handle | GET | 1 |
/channel/latest?channel=@handle | GET | free |
/channel/videos?channel=@handle | GET | 1/page |
/channel/search?channel=@handle&q=Q | GET | 1 |
/channel/playlists?channel=@handle | GET | 1/page |
/channel/posts?channel=@handle | GET | 1/page |
/channel/sections?channel=@handle | GET | 1 |
/playlist/videos?playlist=PL_ID | GET | 1/page |
search also takes type=playlist or type=movie, plus first-page-only filters sort (relevance/views), upload_date, duration, and features. channel/videos takes tab=videos (default), shorts, or streams, plus an optional sort (latest/popular/oldest).
Naming:
/video/metadatawas previously/video/info. The old path still works but is deprecated — use/video/metadata.

Browse channel uploads (paginated):
GET https://transcriptapi.com/api/v2/youtube/channel/videos?channel=@NASA
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0
# Most-viewed first (channel Videos tab, ~30 per page)
GET https://transcriptapi.com/api/v2/youtube/channel/videos?channel=@NASA&sort=popular
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0
# Use continuation token from response for next pages, repeating the same tab and sort
Sorting. Add sort=latest, popular, or oldest to channel/videos to get a channel's videos in the order you want, for example its most-popular uploads first. A sorted page returns about 30 videos (an unsorted page returns about 100), and every page costs the same 1 credit.
When paging, send the same sort on each request.
Item fields. Every item carries members_only, true only when YouTube badges it "Members only", and those items have no viewCountText. tab=streams items carry lengthText and publishedTimeText (for example Streamed 2 years ago); tab=shorts returns null for both, because YouTube's Shorts grid publishes neither. On the channel-tab feeds (tab=videos with sort, tab=shorts, tab=streams) channelId, channelTitle, channelHandle and index are null.
Browse playlist (paginated):
GET https://transcriptapi.com/api/v2/youtube/playlist/videos?playlist=PL_PLAYLIST_ID
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0

Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog.
