Scoring & Ranking

Score each video by:

• views → normalized 0-1 (cap at 10M), weight 0.40
• likes → normalized 0-1 (cap at 500K), weight 0.35
• recency (trending = 1.0 by definition), weight 0.25

score = 0.40 * min(views / 10000000, 1.0) + 0.35 * min(likes / 500000, 1.0) + 0.25

Classification

Edge Cases

• Category not available for country: Some countries only have n (all). Fall back to type=n.
• Stale data: Trending changes throughout the day — data is a snapshot.
• Music/movies category: Returns full songs or trailers — content type differs from regular videos.
• Livestreams in results: isLive=true items are ongoing streams — filter if you need VOD only.
• Country mismatch: gl must be a valid ISO country code (e.g., us, gb, de).
