{"jsonrpc":"2.0","id":1,"method":"tools/list"}validate_card — Validate a credit/debit card number (keyless, offline): Luhn (mod-10) checksum, detected card network (Visa/Mastercard/Amex/Discover/JCB/Diners/UnionPay/Maestro), and whether the length is valid for that network. Spaces/dashes are ignored. NOTE: this checks the number is well-formed — it does NOT verify the card is real/active/funded (that needs a payment processor).check_luhn — Run a raw Luhn (mod-10) check-digit validation on any numeric string (cards, IMEI, national IDs, etc.). Returns whether the check digit is valid and what the correct check digit would be.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
