How this service works
Call when an agent needs whether an IBAN is a mod-97-valid CZ number of length 24. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/check-iban-cz first.
Output
Returns whether the provided string is a valid Czech IBAN: confirms it starts with 'CZ', is exactly 24 characters in length, and passes the ISO 7064 mod-97-10 checksum algorithm. Likely returns a boolean or structured pass/fail result.
Example use cases
Pre-payment Czech IBAN verification
“Before I wire funds to this supplier, can you verify that 'CZ6508000000192000145399' is a legitimate Czech IBAN that passes the mod-97 check?”
Form input IBAN validation
“A user just entered 'CZ0108000000001234567890' as their bank IBAN — can you confirm it's a valid CZ IBAN with the correct length and checksum before I save it?”
Bulk onboarding bank detail check
“We're onboarding a new Czech partner and they gave us 'CZ5503000000000123456789' as their IBAN — is it a valid 24-character Czech IBAN that passes mod-97 validation?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-cz?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate a Czech Republic (CZ) IBAN for mod-97 compliance and correct length (24 characters). It is preferable over generic IBAN validators when the use case is narrowly scoped to CZ IBANs and you want a lightweight, paid microservice call. Try the free sandbox at POST /v1/sandbox/check-iban-cz first before using this paid endpoint.

- IBAN does not start with CZ country code — returns invalid
- Mod-97 checksum fails — returns invalid
