This API is designed primarily for online store owners who want to perform a deep checking of their credit/debit card transactions, it gives a clear vision on how risky the transactions are.
However, anyone can use this API on any platform as he wants and according to his plan limits

How this API works?
The user will send the credit/debit card (Bank Identification Number) or IIN (Issuer Identification Number) to get the full details as possible. Also, if the IP address is given with the request, it will return the IP address details and check the BIN information against the IP information and gives a risk score for the transaction.
It’s very useful for online merchants to help them take the best decision.

How to use this API?
If the user sends the BIN number only, it will return the full details of the BIN.
If the user sends the BIN and the IP address of his client, it will return the full details of the BIN and the details if the IP address as well with a risk score.
