How this service works
Speech-to-text API (audio transcription) for AI agents. Send MP3 or WAV (body, audio_url or base64, up to 30 min); get transcript, language, timestamped segments, optional SRT/VTT; task=translate gives English. $0.003 per audio minute, rounded up; the 402 quotes your file's exact total. Search intents: speech to text api, transcribe audio file, mp3 to text, wav to text, whisper api pay per minute, srt vtt subtitles, podcast transcription.
Output
Returns a JSON object containing the full transcript text, detected language code, an array of timestamped segments (each with start time, end time, and text), billed minutes, duration in seconds, and total cost in USD. If SRT or VTT format was requested, includes the formatted subtitle string in the corresponding field.
Example use cases
Podcast episode subtitles
“I have a 20-minute podcast episode at https://mypodcast.com/ep10.mp3 — can you transcribe it and give me the subtitles as an SRT file so I can upload them to YouTube?”
Multilingual interview transcription
“Please transcribe this Spanish-language interview audio at https://media.example.com/interview.wav — detect the language automatically and give me the full transcript with timestamps for each segment.”
Translate foreign audio to English
“I've got an audio file of a German conference talk at https://conference.example.com/talk.mp3 — can you translate it to English text so I can read what was said?”
Technical details
Endpoint
GEThttps://api.youraitools.co/transcribe/v1/transcribe?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need pay-per-minute audio transcription with timestamped segments and optional subtitle output (SRT/VTT) without a monthly subscription. It is ideal for agents that process variable volumes of audio on demand, need language auto-detection, or require English translation of non-English audio. Prefer it over flat-rate APIs when call frequency is low or file sizes vary widely, since billing is rounded up per minute at $0.003/min.
Side effects
- Audio URL is not publicly accessible or returns a non-200 status — endpoint cannot fetch the file
- File exceeds 30-minute or 30 MB limit — request rejected
- Unsupported audio format supplied — only MP3 and WAV are accepted
- 402 Payment Required returned when credits are exhausted — response body quotes exact cost for the file
- Language code is invalid ISO 639-1 — may fall back to auto-detection or error
- Network timeout for very large files hosted on slow servers
