YouTube Data API for Creators: Find Underserved Topics Free (2026 Guide)

The paid keyword tools you are using to find YouTube topics do not have access to YouTube's actual search data. They estimate. But YouTube publishes a free API that hands you the real comment threads, search rankings, and video statistics the paid tools approximate. This episode covers the plain-English setup (about 15 minutes), the quota math for a free 100K-unit daily budget, comment mining for viewer pain points, and search-gap detection for topics where existing coverage is weak.
