Takes a public URL of an audio or video file of up to 120 minutes and 150 MB and
Takes a public URL of an audio or video file of up to 120 minutes and 150 MB and returns the transcript: full text, paragraphs with sentences and timings, utterances, the detected language, and a confidence breakdown naming the weakest words with timestamps; every word with its timing on request. The file is downloaded and its running time measured locally with ffprobe before anything is sent, so a recording longer than declared is refused with its real length and nothing is charged.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
