For API Rapid Deposit integration and for Pay Outs, we offer our merchants an API that can be used to show an indicative rate to their end-user between the cashier currency and cryptocurrency.
In API Rapid integration Pay ins, the indicative rate would be used by the end-user to deposit the correct amount of cryptocurrency (currency) so that their platform account can be credited with the right amount of local or cashier currency (cashierCurrency).
For pay outs, the indicative rate would inform the user how much cryptocurrency (targetCurrency) they would receive against the cashier or local currency (cashierCurrency) they use on the merchant platform.
