How this service works
Call when an agent needs whether an IBAN is a mod-97-valid AT number of length 20. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/check-iban-at first.
Output
Returns a boolean or structured result indicating whether the provided string passes mod-97 checksum validation and conforms to the Austrian IBAN format (country code AT, exactly 20 characters total).
Example use cases
Validate payee IBAN before wire transfer
“Before I initiate this bank transfer to Austria, can you verify that AT611904300234573201 is a properly formatted and mod-97-valid Austrian IBAN?”
Batch onboarding form IBAN check
“A user just entered AT483200000012345864 as their bank account on our onboarding form — can you confirm it's a valid AT IBAN with the right length and checksum before we save it?”
Detect mistyped Austrian IBAN
“My customer provided what they say is their Austrian IBAN: AT12345678901234567X — can you check if that's actually a valid AT IBAN or if they made a typo?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-at?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to validate an Austrian (AT) IBAN and want country-specific length enforcement (exactly 20 characters) alongside the mod-97 check. Prefer the unpaid sandbox endpoint POST /v1/sandbox/check-iban-at first for testing. Use the generic IBAN validator sibling endpoint instead if the country is unknown or varies. Use this paid endpoint in production flows where Austrian IBAN correctness must be confirmed before a financial transaction.
Side effects
- Input string is not exactly 20 characters — validation fails with format error
- Country code is not AT — endpoint rejects or returns invalid
- Non-alphanumeric characters in the IBAN — validation fails
- Mod-97 checksum does not equal 1 — returns invalid
- Empty or missing value field — request rejected
- Payment not fulfilled (x402) — endpoint returns 402 Payment Required
