Do we have to pay for each use of the Device Fingerprinting SDK?

Device fingerprinting comes free of charge when used together with the IP, Email or Phone APIs. It only incurs extra costs if only the Fraud API and Device Fingerprinting are called in a request.

This would cost the same as a Fraud API + IP API call. We recommend that you use the Fraud + IP APIs as well as the Device fingerprinting module for account_login, deposit, withdrawal, and other, similar transactions, since there is no cost difference between the two methods.
