youtube-channels

Use when a YouTube channel is the focus: pasted @handles or channel URLs, requests to browse a creator's uploads, see what a channel has posted recently, search within a channel, or resolve a handle to a channel ID. Also use when the user names a creator and wants to explore their content or monitor their uploads. Not for creating channels or account management.

YouTube Channels

YouTube channel tools via TranscriptAPI.com.

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.

All channel endpoints accept flexible input — @handle, channel URL, or UC... channel ID. No need to resolve first.

Great for monitoring channels — free and gives exact view counts + ISO timestamps.

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

Paginated list of a channel's feed (~100 per page). Use tab to pick uploads (default), Shorts, or live streams, and the optional sort to order the Videos tab by latest, popular, or oldest.

# First page
GET https://transcriptapi.com/api/v2/youtube/channel/videos?channel=@NASA&tab=videos
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

# 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

Param	Required	Validation
`channel`	conditional	`@handle`, channel URL, or `UC...` ID
`tab`	no	`videos` (default), `shorts`, or `streams`
`sort`	no	`latest`, `popular`, or `oldest` (omit for the uploads feed)
`continuation`	conditional	non-empty (next pages)

Provide exactly one of channel or continuation, not both. When paginating, pass the same tab and sort on every page.

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.

Per-item fields by feed:

Field	uploads (no `sort`)	`tab=videos` + `sort`	`tab=streams`	`tab=shorts`
`lengthText`	populated	populated	populated (`LIVE` while live)	`null`
`publishedTimeText`	populated	populated	populated (`Streamed 2 years ago`)	`null`
`viewCountText`	populated	populated	populated (`null` while live)	populated
`channelId` / `channelTitle` / `channelHandle` / `index`	populated	`null`	`null`	`null`
`members_only`	always `false`	`true` on membership videos	`true` on membership streams	always `false`

members_only is true only when YouTube badges the item "Members only". Such items carry no viewCountText, because YouTube does not publish view counts for membership content.

Response:

{
  "results": [{
    "videoId": "abc123xyz00",
    "title": "Video Title",
    "channelId": "UCsT0YIqwnpJCM-mx7-gSA4Q",
    "channelTitle": "TED",
    "channelHandle": "@TED",
    "lengthText": "15:22",
    "viewCountText": "3.2M views",
    "publishedTimeText": "2 years ago",
    "thumbnails": [...],
    "index": "0",
    "members_only": false
  }],
  "playlist_info": {"title": "Uploads from TED", "numVideos": "5000", "ownerName": "TED"},
  "continuation_token": "4qmFsgKlARIYVVV1...",
  "has_more": true
}

Keep calling with continuation until has_more: false.

GET /api/v2/youtube/channel/search — 1 credit

Search within a specific channel.

GET https://transcriptapi.com/api/v2/youtube/channel/search?channel=@TED&q=climate+change&limit=30
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0

Param	Required	Validation
`channel`	yes	`@handle`, channel URL, or `UC...` ID
`q`	yes	1-200 chars
`limit`	no	1-50 (default 30)

GET /api/v2/youtube/channel/info — 1 credit

A channel's profile: title, handle, verified flag, subscriber/video counts, description, tags, thumbnails, banners, and the tabs it exposes.

GET https://transcriptapi.com/api/v2/youtube/channel/info?channel=@TED
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0

Param	Required	Validation
`channel`	yes	`@handle`, channel URL, or `UC...` ID

Response:

{
  "channelId": "UCAuUUnT6oDeKwE6v1NGQxug",
  "title": "TED",
  "handle": "@TED",
  "verified": true,
  "subscriberCountText": "23.8M subscribers",
  "videoCountText": "4,300 videos",
  "description": "The TED Talks channel features ...",
  "tags": ["TED", "TED Talks"],
  "thumbnails": [...],
  "banners": [...],
  "availableTabs": ["videos", "shorts", "playlists", "community"]
}

Counts are display strings and null when YouTube hides them — never 0. Check availableTabs before calling channel/sections or channel/videos with a tab.

GET /api/v2/youtube/channel/playlists — 1 credit/page

List the playlists shown on a channel — useful for finding a playlist ID to feed into playlist/videos.

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

Param	Required	Validation
`channel`	conditional	`@handle`, channel URL, or `UC...` ID
`continuation`	conditional	non-empty (next pages)

Provide exactly one of channel or continuation, not both. Returns results (playlistId, title, url, videoCountText, thumbnails), continuation_token, has_more.

GET /api/v2/youtube/channel/posts — 1 credit/page

List a channel's community (Posts tab) content — text, publish time, like counts, and any attachment (image, video, playlist, or poll).

GET https://transcriptapi.com/api/v2/youtube/channel/posts?channel=@TED
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0

Param	Required	Validation
`channel`	conditional	`@handle`, channel URL, or `UC...` ID
`continuation`	conditional	non-empty (next pages)

Provide exactly one of channel or continuation, not both. Channels with no community tab return an empty results list (not an error).

GET /api/v2/youtube/channel/sections — 1 credit

The curated shelves on a channel's Home page (or its podcasts/releases pages) — each shelf holds videos, playlists, shorts, or featured channels, in the channel's own order. Not paginated.

GET https://transcriptapi.com/api/v2/youtube/channel/sections?channel=@TED
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0

Param	Required	Default	Validation
`channel`	yes	—	`@handle`, channel URL, or `UC...` ID
`tab`	no	`featured`	`featured` (Home), `podcasts`, `releases`

podcasts and releases only exist on channels that have them (empty results otherwise — check availableTabs from channel/info first).

Typical workflow

# 1. Check latest uploads (free — pass @handle directly)
GET https://transcriptapi.com/api/v2/youtube/channel/latest?channel=@TED
Authorization: Bearer $TRANSCRIPT_API_KEY
User-Agent: YourAgent/1.0

# 2. Get transcript of recent video
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

Stop and check this skill before finishing any reply to a question about how to use Claude or a Claude product — it recommends matching courses, tutorials, and use cases from Claude Academy (academy.claude.com), Anthropic's learning hub. Trigger on: "how do I", "how can I", "getting started with", "what can Claude do", "teach me", "learn to use"; questions about artifacts, projects, skills, plugins, connectors, MCP; requests about rolling Claude out to a team, class, or organization; and any ask for training materials, onboarding content, or learning resources. Use it when the user is learning how to use a feature or product — not when they are mid-task and just want the task done. This skill composes with other skills: after consulting product documentation to answer how a Claude feature works, also check here for a matching course or tutorial — a docs-grounded answer and an Academy recommendation belong together. Only recommend on a strong match; never invent Academy content.
