Brand Sponsorship Data: The Part Most APIs Don't Have.
Which brands has this creator worked with, when, and how did those posts perform? That question decides real influencer marketing budgets, and it is exactly what the eight Brands / Sponsors endpoints answer.
The sponsorship graph works from both directions. Creator-side, Get Sponsorship Information returns a creator's recent sponsored posts and the brands behind them. Brand-side, List Sponsored Creators returns every creator a brand has sponsored on a platform, with the actual sponsored content URLs, sponsored-content engagement rates, and last-sponsored dates. Get Brand Summary adds estimated spend, CPM, and CPE at the brand level.
Below is a complete, unedited response from GET /sponsor/creators?brandId=nordvpn.com&platform=youtube&pageSize=2, captured live on 27 August 2026. Note the scale it implies: 4,412 YouTube creators in NordVPN's sponsored pool, and a single creator with 60 tracked sponsored videos for this one brand.
