Card Validator is a credit card number validator API: it checks whether a card number is valid, identifies the card brand, and flags risk. It runs the Luhn checksum, detects the scheme (Visa, Mastercard, Amex and more), returns the PCI-safe BIN and last 4 digits, flags known processor test cards, and returns a composite risk score.
