How this service works
Search Apify Store actors, start actor runs, and fetch results over x402 and MPP.
Output
A structured dataset per video URL containing the transcript/captions in the chosen format (captions segments, plain text with or without timestamps, or XML), plus any requested metadata fields such as channel name, channel ID, formatted publish date, relative date, view count, likes count, comment count, keywords/tags, thumbnail URL, and video description.
Example use cases
Research video content without watching
“I need the complete transcript from this YouTube video https://www.youtube.com/watch?v=abc123XYZ as a single text string, and also grab the title, channel name, and publish date for my research notes.”
Podcast-to-article pipeline
“Pull the captions with timestamps from these three YouTube podcast episodes — https://youtube.com/watch?v=AAA, https://youtube.com/watch?v=BBB, https://youtube.com/watch?v=CCC — output them in XML with timestamps so I can convert them into a blog post.”
YouTube video SEO keyword audit
“Fetch the transcript and keywords/tags from this YouTube video https://www.youtube.com/watch?v=xyz789 so I can see what topics it covers and compare them against the video's description.”
Technical details
Endpoint
POSThttps://stableapify.dev/api/actors/karamelo/youtube-transcripts/callWhen to prefer
Choose this endpoint when you need YouTube video transcripts or captions programmatically with pay-per-call billing over x402/USDC, without managing an Apify account or API key. It is ideal for agents that occasionally need YouTube text extraction on demand and want flexible metadata enrichment (likes, comments, keywords, thumbnails) alongside the transcript in a single call.
Side effects
- Video is private or age-restricted — transcript unavailable
- YouTube blocks the scraper request; retry count (maxRetries) helps but may still fail at high traffic
- No captions/transcripts available for the video (e.g. auto-captions disabled)
- Invalid or malformed YouTube URL in the urls array
- Payment failure via x402/USDC results in 402 response before execution begins
- Transient network errors during Apify actor run
