# Rumble Video Transcript API

`GET /v1/rumble/video/transcript`

## Request

- Base URL: `https://api.captapi.com`
- URL: `https://api.captapi.com/v1/rumble/video/transcript`
- Auth: one of:
  - HTTP bearer
  - API key in header `X-API-Key`

Rumble published captions as timed segments — parses the .vtt from video-details (not speech-to-text).

Fetches the caption track Rumble already exposes on /video-details (unsigned .vtt URLs), parses cues into segments[{text,startMs,endMs}], and returns the full text. source is always "captions". Pass language to require that track (en matches en-auto); mismatch → 404 language_not_available with availableLanguages (never a silent fallback). No tracks → 404 no_captions. 404 costs 0 credits. No STT fallback on this endpoint. Flat 1 credit on success. Segment shape is shared with /v1/youtube/audio-transcript.
