## About

## What it does
IBAN Validator checks whether a bank account identifier is a valid IBAN and returns the parsed details your application can use.

Send an `iban` string in the request body. The response is either `false` for an invalid value, or a data object containing `iban`, `valid`, `country_code`, `sepa_country`, `bban`, and `printable_format`. That gives you both a simple validity check and the normalized account string in one call.

Use IBAN Validator when you need to gate payment forms, clean up stored banking details, or reject malformed international account numbers before they reach downstream systems. The `country_code` and `sepa_country` fields help you branch logic for regional payment rules, while `printable_format` is useful for showing a formatted version back to users.

The service is narrow by design: it validates a single IBAN value and returns only the fields defined in the response schema. That makes it easy to drop into checkout flows, onboarding steps, and back-office validation jobs without extra parsing work.
