Technical details
Endpoint
GEThttps://api.x-402.online/v1/transcribe?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
