How this service works
Call when an agent needs whether an IBAN is a mod-97-valid FI number of length 18. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/check-iban-fi first.
Output
Returns a boolean or structured result indicating whether the supplied IBAN is a valid Finnish (FI) bank account number: confirms it is exactly 18 characters long, uses the FI country code, and passes the mod-97 checksum algorithm.
Example use cases
Pre-payment IBAN sanity check
“Before I wire money to this Finnish supplier, can you verify that FI2112345600000785 is a valid FI IBAN — correct length, right country code, and passes the mod-97 check?”
Batch onboarding bank account audit
“I'm onboarding a Finnish vendor and they gave me the IBAN FI5542345670000081 — can you validate it's a properly formatted Finnish IBAN that passes mod-97 so I can store it in our system?”
Compliance form IBAN field validation
“A user just entered FI3312345600000098 in the bank account field of our compliance form — can you tell me if it's a legitimate Finnish IBAN with the correct structure and checksum?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-fi?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate a Finnish (FI) IBAN for correctness — both structural length (18 chars) and mod-97 checksum — before initiating a payment, storing banking data, or processing a financial form. Prefer the free sandbox endpoint POST /v1/sandbox/check-iban-fi first during development. For other country IBANs (LT, LU, LV, MK, etc.), use the corresponding country-specific sibling endpoints on the same host.
Side effects
- IBAN string missing or empty — returns validation error
- IBAN is not an FI-prefix number — may return invalid or country mismatch
- IBAN length is not exactly 18 characters — fails validation
- Mod-97 checksum does not pass — returns invalid
- Malformed input (non-alphanumeric characters) — may return parse error
- Payment of $0.005 USDC not provided — returns 402 Payment Required
