POST /api/iban/check

unprobed

Validates an IBAN: country prefix, length, segment-by-segment structure and the ISO 7064 MOD 97-10 check digits, recomputing the correct ones when they are wrong. Checked against the SWIFT IBAN Registry, which also yields bank and branch identifiers and names territories sharing a prefix (Jersey uses GB). Reports every check with status, not only failures, and states what it does not check: exist…

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
