Convert spoken audio or video into text. Send a media_url (mp3, mp4, mpeg, mpga, m4a, wav, or webm) with optional language and task settings, and get back a text transcript. Runs on Whisper v3, auto-detects 90+ languages, supports a translate-to-English mode instead of same-language transcription, and checks media duration up front, rejecting anything over 60 minutes or 500MB before spending time on the job. Use it as a video transcription API, speech-to-text converter, or audio transcript generator for podcasts, interviews, meetings, or any spoken-word source you need in text form. For speaker labels, use the speaker-diarize endpoint.
