Edge Cases
- Category not available for country: Some countries only have
n(all). Fall back totype=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).
