Endpoint
POSThttps://stableapify.dev/api/actors/starvibe/youtube-video-transcript/callWhen to prefer
Use this endpoint when you need to extract the spoken text content of YouTube videos programmatically, especially for summarization, translation, analysis, or archiving. Prefer it over manual caption downloads when automating workflows at scale or when accessing channel-wide transcripts with date filtering. It is particularly well-suited for AI agents needing to ingest YouTube video content as text for downstream processing.
Side effects
- Video has no available captions or subtitles — returns empty transcript
- Invalid YouTube URL format — returns validation error
- Requested language subtitles not available for the video
- Channel URL with no videos matching the date filter — returns empty results
- Actor run timeout for large channel requests
- x402 payment failure — call not executed
