post/validate/v1/iban1 credit

Validate + parse an IBAN offline (ISO 13616 mod-97) → country, BBAN, bank/branch/account. Optional enrich=true adds BIC + bank name/city (openiban.com, proxied).

Working example
Parameters

The IBAN to validate + parse (offline, ISO 13616 mod-97). Spaces and dashes are ignored; case-insensitive. Returns country, check-digits, BBAN, bank/branch/account, and the checksum math.

If true and the IBAN is valid, also fetch BIC + bank name/city from openiban.com (free, proxied). Bank-directory coverage is openiban's supported set (proven live: DE/NL/LU/LI; AT/BE/CH listed but their directory may miss codes). Never changes the validity verdict — the mod-97 result is ours, offline. Default false keeps iban 100% offline.
