Calls you already paid for are never billed again
Compute calls paid per call, taken from a day pass or drawn from a prepaid balance no longer count toward a workspace's billable usage cost, and the usage page shows the split.
A compute call can be paid for when it is made: per call with an x402 payment, from a day pass the workspace bought, or from the workspace's prepaid balance. Those calls used to be added to the workspace's usage cost as well, so a workspace later billed from its usage would have paid for them twice. They no longer are.
A paid call still counts as a request everywhere, in the usage totals, the event list and every limit, and its cost is still shown. It is left out of the billable cost only. The usage summary now reports prepaid_requests and prepaid_cost for the calls already paid for and billable_cost for the rest, and current_period_cost is this month's billable cost, which is zero when every call this month was already paid for. Each usage event carries paid_via (x402, day_pass or balance) when it was paid for, and is null otherwise. A call covered by a free daily allowance was not paid for and is billable as before.
In the dashboard, the usage page's Total Cost card shows the billable cost for the month and, when some calls were already paid for, how much of the total that was and that it is not billed again. Each paid call in the event list is labelled Paid per call, Day pass or Prepaid balance.
