Api Endpoint

IBAN check

Use when an agent must decide whether a bank account it was given can be paid before trying: validates one IBAN offline - country, expected length, ISO 7064 mod-97 check digits, whether it is inside SEPA, and the account number split out. Deterministic, no network call and no third party that can go down. Built for cleaning a list of accounts one at a time.
