How this service works
Fetch a timestamped YouTube transcript so agents do not need to watch the video
Output
A timestamped transcript of the YouTube video, structured as ordered caption entries each containing the timestamp and the spoken text at that moment, enabling agents to read, search, quote, or summarize video content without playback.
Example use cases
Summarize a conference talk
“Get the transcript from this YouTube keynote — https://www.youtube.com/watch?v=abc123XYZ — and summarize the main points for me so I don't have to watch the whole thing.”
Find a specific quote in a video
“Pull the timestamped captions from https://www.youtube.com/watch?v=xyz789ABC and tell me exactly when and what the speaker says about machine learning.”
Non-English video caption extraction
“Fetch the transcript from this Spanish YouTube video https://www.youtube.com/watch?v=esp456DEF — use lang 'es' — so I can translate and understand what's being discussed.”
Technical details
Endpoint
GEThttps://agent-product-normalizer.vercel.app/api/v1/video-transcriptWhen to prefer
Use this endpoint when an agent needs to read, search, quote, or summarize the spoken content of a YouTube video without downloading or playing it. Prefer this over full video analysis endpoints when only the text/caption content is needed and not visual or technical analysis. Choose this when you need raw timestamped captions for downstream processing such as summarization, quote extraction, or translation.
Side effects
- Video has no available captions or auto-generated transcript — returns an error or empty result
- Private or age-restricted video URL is inaccessible — returns an access error
- Invalid or malformed YouTube URL — returns a validation error
- Requested language code has no available transcript — may fall back or return an error
- Video has been removed or is unavailable — returns a not-found error
