{"slug":"best-automated-video-moderation-apis-for-user-generated-content-platforms","title":"Best automated video moderation APIs for user-generated content platforms","question":"What are the best automated video moderation APIs for user-generated content platforms in 2026?","verdict":"As of 2026-09-09, Claude, Gemini and Grok collectively rank Hive Moderation #1 for automated video moderation apis for user-generated content platforms on ModelsAgree — unanimous among the 3 models that have answered. The models' case: The category benchmark for video UGC — dense frame-level sampling plus audio/speech and on-screen-text models across a granular taxonomy (NSFW, violence, gore, drugs. The models' main caveat: Commercial-only and priced per-unit, so high-volume streaming can get expensive. The strongest alternative is Sightengine — Exceptional developer ergonomics with instant self-serve onboarding, transparent pay-per-minute pricing, and turnkey support for both asynchronous.
