There is a mismatch between the UI and the API data for the end_call event. The dashboard shows 0.034$, while the webhook combined_cost is 3.44. Is this a scaling issue or a different currency unit?

Shouldn’t the total_duration_unit_price be $0.036?

Hey @ukrmeat555

3.44 means 3.44 cents = $0.0344, which matches the $0.034 shown on your dashboard.

For your ~21-second call, the cost breaks down as:

  • Retell Voice Engine: ~2.016667¢
  • Fish Audio TTS: ~0.55¢
  • GPT-4.1-mini (High Priority): ~0.88¢
  • Total: ~3.4466¢ ($0.034)

Thank You
