## How to call it through Zero

Example prompt: Can you transcribe the audio from this YouTube video for me? https://www.youtube.com/watch?v=dQw4w9WgXcQ — it doesn't have subtitles so I need actual speech recognition on the audio.

## When to prefer this

Use this endpoint when you need an actual speech-recognition-based transcript of a video hosted on YouTube, TikTok, or Instagram — especially when the video has no subtitle track, the captions are auto-generated and inaccurate, the content is in a non-English language, or the platform (TikTok/Instagram) doesn't expose caption data at all. Prefer this over caption-scraping tools when accuracy matters.

## Known failure modes

- Invalid or inaccessible video URL returns an error
- Private or age-restricted videos cannot be downloaded
- Very long videos may time out or exceed processing limits
- Videos with no spoken audio return an empty or minimal transcript
- Unsupported platforms (not YouTube, TikTok, or Instagram) return errors
- Heavy background noise may reduce transcription accuracy

## How this service works

Transcribe the actual audio of a YouTube, TikTok or Instagram video with Whisper large-v3. Not caption scraping: the audio is downloaded and run through speech recognition, so it works on videos with no subtitles, in any language, and on TikTok and Instagram where no caption track…

## Output

A text transcript of the spoken audio in the video, produced by Whisper large-v3 speech recognition running on the downloaded audio track. Works regardless of whether the video has captions, supports any language, and covers YouTube, TikTok, and Instagram.
