I built an IBAN validation API for developers

Hey!

I built a simple API that handles all the complexity of international bank account validation. It covers 80+ countries, knows all the special rules (like Bulgaria's account types, Germany's bank codes or French RIB codes), and gives you reliable bank information in return (if possible)

No complicated integration, no maintenance headaches - just send the IBAN, and get back everything you need to know about its validity, the bank, and its SEPA capabilities.

For more background, a few months ago some friends running fintech businesses came to me with a common headache - validating international bank accounts was causing payment failures and support tickets. They were either using basic IBAN validators (missing country-specific rules) or paying for expensive enterprise solutions.

And this is how SecureIBAN was born.

I'm really excited to share this with other developers / founders who might be struggling with the same problem. Would love to hear your thoughts or answer any questions!
