The IBANforge API checks an IBAN and names the bank behind it, with its BIC when one is known, reading national registers such as the one on this page. Two ways to start without paying:
Keyless trial
Send an IBAN to POST /v1/iban/validate with no key at all, up to 25 times a week, on that route only. With this page’s example IBAN:
curl -X POST https://api.ibanforge.com/v1/iban/validate \
-H "Content-Type: application/json" \
-d '{"iban":"DE59810104001000000000"}'Free key
200 requests a month on every endpoint once you add an e-mail address and confirm the code sent to it. With no address and no card, it starts at 25 requests a month, straight away.
