Example prompt: Can you transcribe this audio recording for me? Here's the base64-encoded WAV file — just give me the text of what was said.

## When to prefer this

Choose this endpoint when you need fast, pay-per-use English speech-to-text transcription without API key setup, using USDC micropayments on any supported chain (Base, Polygon, Arbitrum, World, Solana). Ideal for lightweight, low-cost ASR tasks where Whisper Tiny EN accuracy is sufficient and you want to avoid subscription-based ASR services.

## Known failure modes

- Invalid or corrupt base64 audio data returns an error
- Non-English audio may produce poor or garbled transcriptions since the model is English-only
- Audio too long or too large may exceed processing limits
- Payment failure on the chosen chain (Base, Polygon, Arbitrum, World, Solana) results in a 402 response and no transcription
- Missing or empty audio parameter returns a bad request error
