YouTube Brand Mention Finder

YouTube

Operated by Sourcelane✓ verified

A YouTube-focused brand mention and sponsorship detection connector that searches for creators who promote a given brand, domain, or promo code and extracts structured signals from video metadata and descriptions. It locates and classifies mentions (sponsorships, affiliate/tracking links, promo codes, generic mentions), unwraps redirection links to reveal destination URLs, extracts promo codes and disclosure text, and computes per-mention video and channel metrics such as view counts, upload date, video duration, channel name and subscriber counts. The connector also offers an aggregated creator mode that consolidates mention counts, sponsored-mention counts, total and average views for a creator’s mentions, and the list of related videos, enabling reverse sponsorship discovery and link/code attribution across channels.

Call it via Sourcelane

curl -X POST https://cool-puffin-608.convex.site/v1/call \
  -H "Authorization: Bearer sl_live_your_agent_key" \

Request params

Field	Type	Required	Description
`brands`	array	required	What to look for, one per line: a brand name (Squarespace), a domain (athleticgreens.com) or a promo code (NORD20). Each line is searched separately - add your own variants to widen the net.
`maxVideosPerBrand`	integer	optional	How many search results to open and read per brand term. Videos that do not actually mention the brand are dropped, so this is the search depth, not the result count.
`mode`	string	optional	Per-video rows give you every mention; per-creator rows give you an outreach list with each creator's mentions grouped together.
`sponsoredOnly`	boolean	optional	Keep only videos with a sponsor disclosure, an affiliate link or a discount code - drop videos that merely name the brand.
`uploadedWithin`	string	optional	Limit the search to recent uploads - useful for tracking a campaign that is running now.
`sortBy`	string	optional	How YouTube orders the videos that get checked.
`minViews`	integer	optional	Skip videos with fewer views than this. 0 keeps everything.

Each result contains

Field	Type	Description
`brand`	string	Brand
`mentionType`	string	Mention Type
`isLikelySponsored`	boolean	Is Likely Sponsored
