How this service works
Validate International Bank Account Numbers: ISO 13616 country/length check plus the ISO 7064 mod-97 checksum. Returns the country, check digits, and the BBAN. Single IBAN or a batch of up to 50. Validates structure and checksum, not that the account is open. POST a JSON body like: {"iban":"DE89 3704 0044 0532 0130 00"}
Output
Returns the country code, check digits, and BBAN parsed from the IBAN, along with a validity flag indicating whether the ISO 13616 structure and ISO 7064 mod-97 checksum are correct. For batch requests, results are returned per IBAN.
Example use cases
Example prompt
“Can you validate this IBAN and tell me the country, check digits, and BBAN: DE89 3704 0044 0532 0130 00?”
Technical details
Endpoint
POSThttps://keyronne.com/api/iban?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate and parse IBANs before processing international bank transfers, onboarding users, or verifying payment details. Ideal for single lookups or batch validation of up to 50 IBANs at once. Note: it validates format and checksum only, not whether the account is actually open.
Side effects
- Invalid IBAN format returns a validation error with reason
- IBAN fails mod-97 checksum returns invalid result
- Unsupported or unknown country code may fail structure check
- Batch exceeds 50 IBANs returns a 400 error
- Malformed JSON body returns a 400 parse error
