Use this endpoint when you need to validate a French IBAN's integrity via mod-97 checksum and also extract the embedded French bank code in a single call. Ideal for KYB/KYC workflows, payment onboarding, or any scenario requiring French banking account verification without a full bank lookup service.
Side effects
- Invalid IBAN format returns validation failure
- Non-French IBANs may return no bank code
- Malformed query string returns error
- Empty or missing iban parameter returns bad request
- IBANs with incorrect checksum flagged as invalid
