IBAN validation and BIC lookup with a free keyless demo
IBANforge validates IBANs and looks up BIC/SWIFT codes across dozens of countries, backed by 121K+ BIC entries. The keyless /v1/demo endpoint returns worked examples showing the full validation shape (country, check digits, BBAN, SEPA reachability, BIC). Live queries need a free API key or an x402/USDC micropayment.

IBANforge: common questions
Is IBANforge free to use?
Yes — IBANforge is a free finance API. Free tier: 200 requests/month with a free API key; /v1/demo and /health are keyless. Whether the free tier allows commercial use is unclear — check the provider docs.
Does IBANforge need an API key?
No — IBANforge needs no API key or signup. You can call it straight away; rate limits still apply (Unpublished (200/month free quota)).
Can I call IBANforge from the browser?
Yes — IBANforge returns CORS headers over HTTPS, so front-end code can fetch it directly with no backend proxy. Use the fetch snippet on this page, or hit "Run live" to try it now.
Is IBANforge up right now?
As of our last scheduled check, IBANforge is unmonitored. We re-probe it every sweep — the status badge and uptime chart above always show the latest.
