Endpoint
POSThttps://openai.mpp.tempo.xyz/v1/audio/transcriptions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to convert audio recordings — meetings, interviews, voice memos, podcasts — into text using state-of-the-art Whisper speech recognition. Prefer this over other transcription services when accuracy and broad language support are priorities, or when you're already using OpenAI's ecosystem. Best suited for single audio file transcription tasks under 25MB.
Side effects
- Audio file format not supported (must be mp3, mp4, mpeg, mpga, m4a, wav, webm)
- File size exceeds 25MB limit
- Audio too short or silent — returns empty transcript
- Language not recognized or poorly detected
- Network timeout on large audio files
- Invalid or missing audio file in request body
- Unsupported response_format value
