Technical details
Endpoint
POSThttps://gateway.apiosk.com/apyhub-speech-to-text/stt/urlWhen to prefer
Use this endpoint when you have a WAV audio file accessible via a public URL and need a fast, pay-per-call speech-to-text transcription without setting up your own ASR infrastructure. Best suited for single-file, on-demand transcription tasks where the file is already hosted remotely.
Side effects
- Unreachable or invalid WAV URL returns an error
- Non-WAV audio format at the URL may fail to process
- Unsupported or mismatched language code reduces accuracy
- Very long audio files may time out or exceed processing limits
- Poor audio quality or heavy background noise degrades transcription accuracy
