The Card Tools are a set of utility endpoints that let you work with card BIN/IIN data. The BIN (Bank Identification Number), also known as IIN (Issuer Identification Number), is the first 6 to 11 digits of a card number. These digits identify the card’s brand, issuing bank, country of origin, and card type. All Card Tools endpoints are authenticated with your API key. Both the input (the first 6–11 digits of the card number) and the output are considered non-sensitive data — the BIN/IIN alone cannot identify a cardholder or be used to initiate a transaction, so calling these endpoints does not put you in PCI scope.
