FAQ
What are minor units?
The smallest unit of a currency, like cents for USD. Payment APIs such as Stripe and Adyen take amounts as an integer in minor units: 10.00 USD is sent as 1000.
Which currencies have no decimals?
Zero-decimal currencies include JPY, KRW, VND, CLP, ISK, XAF and XOF: 500 JPY is sent as 500. Three-decimal currencies include KWD, BHD, OMR, JOD and TND: 1.000 KWD is sent as 1000.
Where do the exchange rates come from?
Daily reference rates published by central banks (via the open-source Frankfurter API). Your bank or payment provider applies its own rate and fees.
