TL;DR

Rumble published captions as timed segments — parses the .vtt from video-details (not speech-to-text). The Rumble Video Transcript API (Rumble) is a single authenticated GET request to /v1/rumble/video/transcript that responds with clean JSON and costs 1 credit. Pass cache=true for a free 24h cache hit; default is always fresh. Start with 100 free credits — no credit card.

What is the Rumble Video Transcript API?

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.

What you get

source always "captions" on success
Uniform segments[{text,startMs,endMs}] (shared shape)
Rolling auto-caption duplicates collapsed
404 language_not_available / no_captions cost 0
