Request a transcript
Send a JSON POST to /api/v1/youtube/transcript with a direct public YouTube watch, youtu.be, or Shorts URL. An optional language code must match one of the languages returned for that video. Leave it out to choose an available manual track first, with English preferred when present.
The endpoint currently needs no API key. It is a rate-limited public preview, not a bulk or paid API. Build retry handling for HTTP 429 and do not assume every public video has accessible captions.
Example request
curl -X POST https://savefromnet.fun/api/v1/youtube/transcript \
-H "Content-Type: application/json" \
-d '{"url":"https://www.youtube.com/watch?v=VIDEO_ID"}'Understand the response
A successful response includes the normalized video URL, title, author, duration when available, selected language, manual or automatic track kind, available caption languages, and segments with start_ms, end_ms, and text. Millisecond timing is from the source caption track.
The API returns JSON cues. The browser tool can also create TXT, SRT, and VTT exports from the same result. Captions may be inaccurate, especially automatic tracks; verify quotations against the original video before reuse.

}Errors and limits
Invalid or unsupported URLs return a JSON error. Missing captions, unavailable languages, private or restricted videos, and source failures are reported without inventing transcript text. Requests are capped at 4 KB; caption tracks and segment counts also have safety limits.
The API accepts one video per request. It does not fetch playlists, bypass sign-in or other access controls, translate captions, or run audio recognition. Use only content you own or have permission to process.
Developer subscription
The authenticated /api/v2/youtube/transcript endpoint is designed for developer use. The plan is $5 per month for 1,000 successful transcripts in each billing period. Failed extraction does not consume the allowance. Requests are limited to four per minute and two active extractions per account.
Open the developer dashboard to check checkout availability, subscribe, create or rotate your API key, and see usage. Send Authorization: Bearer YOUR_API_KEY with the same JSON body as the public preview. Keep both the API key and the account recovery code private.
