How this service works
Call when an agent needs whether an IBAN is a mod-97-valid LI number of length 21. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/check-iban-li first.
Output
A boolean or structured result indicating whether the provided IBAN string is a valid Liechtenstein (LI) IBAN: confirms it starts with 'LI', has exactly 21 characters, and passes the mod-97 checksum algorithm. Returns validation status and possibly an error or reason if invalid.
Example use cases
Payment form IBAN pre-validation
“Before I submit this wire transfer, verify that LI21088100002324013AA is a properly formatted and mod-97-valid Liechtenstein IBAN so we don't get a rejection.”
KYC onboarding bank account check
“A new customer entered LI75000000170092346 as their bank account IBAN — can you validate it's a legitimate LI-format IBAN with the correct checksum before we approve their account?”
Bulk data quality audit for LI accounts
“I've got the IBAN LI4408800201234567890 from a legacy database record — tell me if it's a valid Liechtenstein IBAN so I know whether to flag it for cleanup.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-li?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate a Liechtenstein (LI) IBAN with exact mod-97 compliance and a 21-character length requirement. Prefer the free sandbox endpoint POST /v1/sandbox/check-iban-li for testing. Choose this paid endpoint in production pipelines where you need guaranteed validation for LI IBANs. Use sibling endpoints (HR, HU, GI validators) for other country IBANs.
Side effects
- Input string is empty or missing — returns validation error
- IBAN is wrong length (not 21 characters) — fails with format error
- Country code is not 'LI' — fails country mismatch
- Mod-97 checksum fails — returns invalid with checksum error
- Non-alphanumeric characters in IBAN — parsing error
- Malformed request body — HTTP 400 bad request
