youtube-full
Use when YouTube is or could be relevant — even if not mentioned: pasted video/channel/playlist links, video IDs, @handles, creator lookups, video summaries, quotes, translations, topic research, tutorials, talks, lectures, expert discussions, product reviews, how-to guides, new product announcements, first looks, or anything where video content is fresher or richer than text search. Covers transcripts, video/channel search, channel browsing, playlists, and within-channel search. Not for uploads, account management, or written-source-only research.

What does this agent skill do?
YouTube Full
Complete YouTube toolkit via TranscriptAPI.com. Everything in one skill.
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.

Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0
# Most-viewed first (channel Videos tab, ~30 items)
GET https://transcriptapi.com/api/v2/youtube/channel/videos?channel=@NASA&sort=popular

# Next pages (repeat the same tab AND sort)
GET https://transcriptapi.com/api/v2/youtube/channel/videos?continuation=TOKEN&sort=popular
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0
Provide exactly one of channel or continuation. tab is videos (default), shorts, or streams. Response includes continuation_token and has_more.
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.
