Common questions about our YouTube Transcript API service
The YouTube Transcript API is a professional service that extracts accurate, timestamped transcripts from YouTube videos in multiple languages. It provides developers with easy access to video transcript data for applications like accessibility, content analysis, and AI training.
Our YouTube Transcript API provides high-accuracy transcripts with millisecond-level timestamps. The accuracy depends on the original video's audio quality and whether auto-generated or manual captions are available. We support both auto-generated and human-created transcripts.
We support multiple languages based on availability of languages in the video.
Auto-generated transcripts are created automatically by YouTube's speech recognition technology, while manual transcripts are created by humans. Manual transcripts are typically more accurate but not available for all videos. Our API provides access to both types when available.
Our YouTube Transcript API can only extract transcripts from publicly available videos that have captions enabled. Private, unlisted, or videos without captions cannot be processed through our service.
Rate limits depend on your subscription plan: Free tier allows 60 requests/minute, Professional plan allows 300 requests/minute, and Enterprise plans offer custom rate limits. All plans include generous monthly credit allowances.
If a video doesn't have transcripts available, our API will return an appropriate error message. You can check the 'transcriptLanguages' field in the video info endpoint first to see what transcript languages are available before making a transcript request.
Yes, our YouTube Transcript API operates within YouTube's terms of service by accessing only publicly available transcript data. We don't scrape or violate any platform policies, ensuring your applications remain compliant.
