How this service works
Call when an agent needs whether an IBAN is a mod-97-valid XK number of length 20. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/check-iban-xk first.
Output
Returns whether the submitted string is a valid Kosovo (XK) IBAN: confirming it is exactly 20 characters long and passes the ISO 7064 mod-97 checksum algorithm, or indicating which condition failed.
Example use cases
Pre-payment Kosovo IBAN check
“Before I wire money to this Kosovo supplier, can you verify that 'XK051212012345678906' is a valid XK IBAN — correct length and mod-97 checksum?”
Bulk onboarding bank account validation
“I'm onboarding a new vendor from Kosovo and their bank account is 'XK051234567890123456' — can you confirm this IBAN is properly formatted and passes validation?”
Payment form IBAN verification
“A user entered 'XK0512120123456789' in our payment form for a Kosovo account — is this a valid Kosovo IBAN or should I show them an error?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-xk?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate a Kosovo (XK-prefix) IBAN and require both length (20 chars) and mod-97 checksum verification in a single call. Prefer the free sandbox endpoint POST /v1/sandbox/check-iban-xk first for testing; use this paid endpoint in production. Do not use for IBANs from other countries.
Side effects
- IBAN is not 20 characters — fails length check
- Non-XK country code — endpoint only validates Kosovo IBANs
- Mod-97 remainder is not 1 — checksum failure
- Empty or missing value field — request rejected
- Value exceeds 20000 character limit — unlikely but schema-enforced
