How this service works
Validate an IBAN checksum and decode its country and BBAN, validate a US ABA routing number, check SWIFT/BIC format, or Luhn-check a card and detect its network. Auto-detects the kind if not given.
Output
Returns a JSON object indicating whether the input is valid, the detected instrument type (IBAN, ABA, SWIFT/BIC, or card), the checksum/format result, and decoded metadata such as country code, BBAN (for IBAN), bank name or identifier, or card network (Visa, Mastercard, Amex, etc.).
Example use cases
Validate IBAN before wire transfer
“Before I send an international wire, can you validate this IBAN — GB29NWBK60161331926819 — and tell me if the checksum passes and what country and bank it points to?”
Verify routing number for ACH payment
“I need to confirm this US routing number is legitimate before setting up a direct deposit: 021000021 — can you check it for me?”
Detect card network before checkout
“Run a Luhn check on this card number — 4111111111111111 — and tell me what card network it belongs to and whether the number is valid.”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/iban-routing-validateWhen to prefer
Choose this endpoint when you need to validate or decode financial identifiers — IBANs, US ABA routing numbers, SWIFT/BIC codes, or credit/debit card numbers — without building your own validation logic. It is especially useful in payment workflows, onboarding forms, or data quality pipelines where you need to verify user-supplied banking details before sending them downstream. The auto-detection feature makes it convenient when you don't know in advance what kind of identifier a user will provide.
Side effects
- Invalid or malformed input returns a validation failure with a descriptive error message
- Unsupported instrument type returns an error if auto-detection cannot classify the input
- Checksum failure on IBAN returns invalid with checksum mismatch detail
- Non-existent or unrecognized BIC format returns format error
- Network or timeout errors return HTTP 5xx responses
