How this service works
Call when an agent needs whether an IBAN is a mod-97-valid SK number of length 24. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/check-iban-sk first.
Output
Returns a boolean or structured result indicating whether the supplied string is a valid SK-country-code IBAN of exactly 24 characters that passes the ISO 13616 mod-97 checksum algorithm; no network lookup or external ledger check is performed.
Example use cases
Pre-payment IBAN sanity check
“Before I wire money to this Slovak supplier, can you verify that SK3112000000198742637541 is a legitimate SK IBAN — correct length and mod-97 valid?”
Form input validation for fintech app
“A user just entered SK0900000000004854775648 as their bank account on our checkout form — can you confirm it's a properly formatted and mod-97-valid Slovak IBAN before we accept it?”
Batch invoice IBAN audit
“I have this IBAN from an invoice — SK8109000000000123456781 — can you tell me if it's a valid 24-character Slovak IBAN with a passing mod-97 checksum?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-sk?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a pure algorithmic, offline mod-97 checksum and length validation of a Slovak (SK) IBAN with no external lookups. It is the right choice when you already know the country is Slovakia and need fast, deterministic validation without network dependencies. Use the free sandbox endpoint POST /v1/sandbox/check-iban-sk first to avoid charges during development.
Side effects
- Invalid or missing 'value' field returns an error
- String not starting with 'SK' fails country-code check
- String not exactly 24 characters fails length validation
- String failing mod-97 arithmetic returns invalid result
- Malformed JSON body causes 400-class error
- Payment of $0.004 USDC required; missing payment header returns 402
