How this service works
Call when an agent needs whether an IBAN is a mod-97-valid FO number of length 18. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/check-iban-fo first.
Output
A boolean or structured response indicating whether the provided string is a valid Faroese (FO) IBAN: correctly formatted to 18 characters and passing the mod-97 checksum algorithm.
Example use cases
Validate payee IBAN before wire transfer
“Before I send the payment, can you verify that FO5400400440116243 is a valid Faroese IBAN so I know the account number is correct?”
Fintech onboarding IBAN verification
“A new customer entered FO2000400440116243 as their bank account number — can you check if it's a properly formatted and valid Faroe Islands IBAN?”
Batch payment file pre-validation
“I have this IBAN listed for a Faroe Islands supplier: FO1234567890123456 — can you run a mod-97 validity check on it before I submit the payment batch?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-fo?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate a Faroe Islands (FO) IBAN of exactly 18 characters and want mod-97 checksum verification. It is a focused, cheap ($0.003 USDC) single-country validator. Prefer the free sandbox endpoint /v1/sandbox/check-iban-fo for testing. Use sibling endpoints for other country IBANs (LT, LU, LV, MK, MR, PK, PS, etc.).
Side effects
- Input string is not 18 characters — validation returns invalid
- IBAN does not start with 'FO' country code — fails format check
- Mod-97 checksum fails — IBAN structurally plausible but mathematically invalid
- Empty or null value submitted — request rejected
- Non-string or oversized input exceeding schema limits — rejected
