How this service works
OpenAI-compatible speech to text (Whisper large v3 turbo): multipart file upload exactly like OpenAI /v1/audio/transcriptions, with response_format json, text, srt, vtt or verbose_json. Also accepts a public audio url. Up to 20 MB, flat price, no API key. Also callable as GET with the same fields as query parameters.
Output
Returns the transcription of the audio in the requested format: plain text ('text'), JSON object with a 'text' field ('json'), SRT subtitle format ('srt'), WebVTT subtitle format ('vtt'), or a detailed JSON object including segments and timestamps ('verbose_json').
Example use cases
Podcast episode transcription
“Transcribe this podcast episode for me — the audio is at https://mypodcast.com/episode42.mp3 — and return the full text transcript in plain text format.”
Auto-generate video captions
“I need VTT captions for this interview recording at https://cdn.mysite.com/interview.wav so I can add them to my video player — can you generate those?”
Multilingual meeting transcription
“Please transcribe this French meeting recording at https://storage.mycompany.com/meeting-fr.mp3 and return verbose JSON so I can see word-level timestamps — the language is French.”
Technical details
Endpoint
GEThttps://agents.torbrooknews.com/v1/audio/transcriptions?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a flat-rate ($0.01 USDC), no-API-key speech-to-text solution compatible with the OpenAI Whisper API, especially when you want multiple output formats (SRT, VTT, verbose_json) or need to transcribe from a public URL without uploading a file. Prefer over OpenAI directly when avoiding API key management or when cost predictability matters.
Side effects
- Audio file exceeds 20 MB limit — request rejected
- Invalid or inaccessible public URL — cannot fetch audio
- Unsupported audio format — transcription fails
- Incorrect response_format value — may return error or default format
- Network timeout for large files — partial or no response
