YouTube Playlist Items API reference

YouTube playlist id (the value after list= in a playlist URL).

Pagination cursor from a previous response: fetches the next page.

YouTube channel id: pages that channel's uploads instead of a playlist.

Set to engagement, channel, or both (engagement,channel) to fill more of every row in this one call. engagement fills post.engagement.views, .likes and .comments, post.content.duration_seconds, author.id and post.author.display_name where the row lacks them, and replaces a date derived from a label such as "4 months ago" with the exact publish time (removing post.ext.published_precision). channel puts the channel's subscriber count on post.ext.author_followers (YouTube's own figure, which it rounds to three significant figures above 1,000) and fills the channel's post.author.display_name, .avatar_url and .username where missing. Send both to cover rows that arrive without a channel id: the video join supplies it and the channel join then uses it. Each join adds 0.2 to 0.7 seconds on a fresh page (one lookup per 50 ids, never more than 8 seconds).

Only rows published on or after this date: YYYY-MM-DD (midnight UTC) or an ISO 8601 timestamp. Rows older than it are left off each page. This list is not in date order, so the walk does not stop at the date: keep following next_cursor, and each page costs what a page costs even when every row on it is filtered out. A row with no date is kept.

Only rows published on or before this date: YYYY-MM-DD (that whole UTC day is included) or an ISO 8601 timestamp. Newer rows are left off each page and the walk does not stop, so older pages follow. A row with no date is kept.

Set to 1 to get the price of this call without making it: data.dry_run carries credits_min and credits_max. Nothing is charged.
