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 channel tools via TranscriptAPI.com.
If $TRANSCRIPT_API_KEY is not set, read references/auth-setup.md and follow the instructions there to get and store the key.
Every request needs two headers:
Bearer $TRANSCRIPT_API_KEYHermesAgent/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.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.
Convert @handle, URL, or UC... ID to canonical channel ID.

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