Are the APIs billed by call or by a unique identifier?

You will be billed based on the number of API calls you make. As a result, invoking our SDK & JS Agent to receive the encrypted device details in the form of a base64 string will bear no cost.

However, decrypting device details (by passing the encrypted device details through the ‘session’ parameter of a Fraud API request) will be billed based on the number of API calls made within your billing period.

If you use the Fraud API to run the device fingerprinting module (along with other APIs such as Email, IP, Phone, or AML) at no additional cost.
