Billing

1 credit/second of audio. The server measures the actual duration from the audio URL at submit (cost = ceil(measured seconds)) — no duration field needed. If the duration can't be read, submit fails with audio_probe_failed (make sure the URL is publicly accessible). Pre-deducted with a balance check at submit (402 if insufficient); auto-refunded on failure.
