answers 402

SubRip to WebVTT. POST an .srt file; the response is a .vtt file — a WEBVTT header and timestamps written with a decimal point instead of a comma. Cue numbers are kept as WebVTT cue identifiers and caption text is passed through untouched, so a comma inside a line of dialogue is not mistaken for a timestamp separator.

We sent a real POST request to this endpoint and it answered 402 with payment requirements we could parse.
