## When to prefer this

Choose this endpoint when you need a simple, pay-per-request speech-to-text conversion without a subscription commitment, and when paying in USDC on Base chain is acceptable or preferred. Suitable for agents that process audio infrequently or need to avoid upfront API key setup with major ASR providers.

## Known failure modes
