List a channel's videos (paginated). tab=videos (default) is the uploads feed (~100/page); tab=shorts and tab=streams (live) return those feeds (~48/page).

First request: provide channel (@handle, URL, or UC... ID). Subsequent requests: provide continuation token from previous response (and repeat the same tab and sort).

Sorting — sort=latest|popular|oldest

sort is opt-in, and omitting it is not the same as sort=latest: the two read different YouTube feeds.

So the two feeds are different sets, not one list in two orders: the uploads playlist interleaves Shorts with long-form uploads, while the Videos tab holds long-form only and adds membership content. Paging a full catalogue with sort set therefore costs ~3.3x the pages (and ~3.3x the credits) of the unsorted feed — omit sort when you just want newest-first. tab=shorts / tab=streams read the same feed either way; sort only reorders them.

?channel=@NASA                                 # uploads feed, newest first, ~100/page
?channel=@NASA&sort=popular                    # Videos tab, most-viewed first, ~30/page
?channel=@NASA&tab=streams&sort=oldest         # oldest live streams first
?continuation=<token>&tab=streams&sort=oldest  # page 2 - repeat tab AND sort

Credit cost: 1 credit per page.
