There's no dedicated Billing API to get usage or billing data directly from Retell. [(1) ](

To track costs, you have a couple of options:
1.
Use the List Calls API to get individual call costs and aggregate them on your side.
2.
Set up webhooks to log call costs in your own database.
You can also view usage breakdowns manually in the
Billing > Usage tab on the dashboard, which shows total cost, call minutes, average cost per minute, and cost by provider. [(2) ](
