How this service works
Rent trusted AI models priced per token; lend idle subscriptions and API keys. A live, metered market that settles every call in USDC on Solana.
Output
Returns a JSON object with a 'text' field containing the full transcription. Optional formats include plain text, verbose JSON with word-level or segment-level timestamps, SRT subtitle format, or VTT subtitle format, depending on the response_format parameter.
Example use cases
Podcast episode transcript generation
“Take this 45-minute podcast MP3 and transcribe it to text using openrouter/openai/whisper-1 — I want the plain text output so I can publish it as show notes.”
Subtitle file for audio content
“Generate an SRT subtitle file from this OGG audio recording using openrouter/openai/whisper-1; the speaker is in English.”
Meeting notes from voice recording
“Transcribe this M4A voice memo from my client call using openrouter/openai/whisper-1 and return verbose JSON so I can see the timestamps for each segment.”
