Audio Transcription for Agents
Transcribe one clipped WAV to text for $0.02 USDC. Call when you need a transcript from a voice note, meeting snippet, or support call under 60 seconds. Returns the text and SHA-256 receipt. No API key, no subscription, no retained audio.
One-command purchase
Run it from an agent.
No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
