How billing works
When you submit a transcription, we reserve the estimated cost from your balance based on the audio duration. Once the transcription completes, we charge the exact cost and release any unused reserve.
Cost is calculated as: (audio_seconds / 3600) * $0.20
Failed transcriptions are free. If a job fails for any reason, the full reserve is released back to your balance. You are never charged for unsuccessful attempts.

| 30 minutes | 0.5h | $0.10 |
| 1 hour | 1h | $0.20 |

Rate limits
Rate limits are enforced per API key to ensure fair usage. See the API Reference for specific limits per endpoint. You must also have sufficient balance to cover the estimated cost before a transcription can begin. If your balance is insufficient, the request will return a 402 error.
