Technical details
Endpoint
GEThttps://api.socialfetch.dev/v1/youtube/videos/transcriptWhen to prefer
Use this endpoint when you need the spoken content of a YouTube video as text, such as for summarization, search, analysis, or accessibility purposes. Prefer this over manual caption extraction when you have a direct YouTube URL and need a fast, structured transcript response.
Side effects
- Video URL is invalid or not a YouTube URL — returns error
- Video has no captions or transcript available — returns empty or error
- Requested language code not available for that video — may fall back to default or return error
- Video is private or age-restricted and inaccessible — returns error
- Malformed or missing 'url' query parameter — returns validation error
