  • Hourly metering counts how many wallets exceed the included quota at the end of each hour.
  • Charges accumulate across the month and are added to your base subscription at the end of the billing period.
  • To reproduce the hourly charge, divide the monthly overage rate by the number of hours in the billing period and multiply by the measured wallet-hours above the allowance.

Invoicing

  • Overages appear as a single line item on the monthly invoice labelled “Wallet overage”.
  • Each invoice details the total extra wallet-hours and the rate applied for your plan.
  • Invoices are issued on the calendar date you originally subscribed or upgraded to the current plan.

Payment terms and suspension

  • Payment is due upon receipt of the invoice.
  • If an invoice remains unpaid for 7 days, the account is suspended. API requests return HTTP 402 until the balance is cleared.
  • Pay the outstanding invoice to restore access immediately; no data is deleted during suspension.
