Collabs

Channels that do collabs, meaning videos YouTube lists under more than one channel. Data comes from Algrow's collab sweep, which checks channels' Videos tabs around the clock. Growth figures refresh every 6 hours; partners and videos show up as soon as the sweep finds them.

TOOL fastest_growing_collab_channels

Ranks every channel that appears on a collab video by subscriber or view growth over the last 7 or 30 days. Each channel comes with its growth, how many different channels it has collabed with, how many collab videos it has and when its latest one went out. Growth figures refresh every 6 hours. With sort='pct' the ranking is growth as a percentage of where the channel started, and only channels with at least 1,000 subscribers count unless you set min_subscribers.

Example prompts

"Which collab channels gained the most subscribers this week?"

"Find English channels under 50K subs growing fastest through collabs in the last 30 days"

Find small channels growing through collabs, then see who they collab with

Call fastest_growing_collab_channels with sort='pct' and max_subscribers set, for example 50,000.
Pick a channel from the list and pass its channel_id to get_channel_collabs.
Read its partners to see which channels it works with and how often, and its videos to see what the collabs were about.

TOOL get_channel_collabs

A channel's collab partners and collab videos, newest first. has_new_collab is true when it has a collab video published in the last since_days days. A publish date in the future is an upcoming premiere. Also returns the latest collab date, the channel's 7 and 30 day growth, every partner with how many videos they made together and when they last did, and each video's host channel and full list of collaborators. checked=false means Algrow has not scanned this channel for collabs yet.

Example prompts

"Who does @rachelbakes collab with?"

"Has this channel put out a new collab in the last two weeks?"

Parameter	Type	Default	Description
channel_id	string	required	YouTube channel ID (`UC...`). Use `resolve_handle` first for a @handle or URL.
since_days	integer	7	A collab published in the last N days counts as new.
limit	integer	30	Max partners and max videos returned, up to 100.

TOOL recent_collabs

A feed of collab videos published in the last N days, newest first or most viewed first, across every channel the sweep has checked. Each video comes with its host channel and every collaborator. Pass channel_ids to watch a set of channels for new collabs.
