How this service works
Call when an agent needs whether an IBAN is a mod-97-valid BE number of length 16. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/check-iban-be first.
Output
A boolean or structured response indicating whether the submitted string is a valid Belgian IBAN: passes the mod-97 checksum algorithm, starts with 'BE', and is exactly 16 characters in length.
Example use cases
Payment form IBAN pre-validation
“Before I process this invoice payment, check if BE43068999999501 is a valid Belgian IBAN so we don't send money to a bad account.”
Customer onboarding bank account check
“A new customer entered BE71096123456769 as their bank account — can you verify it's a properly formatted and mod-97-valid Belgian IBAN before we save it?”
Bulk supplier data quality audit
“I have a supplier record with IBAN BE62510007547061 — validate it's a legitimate Belgian IBAN with the correct length and checksum before we add it to our payment system.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-be?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need to validate a Belgian (BE) IBAN. It is purpose-built for the BE country code and 16-character length constraint with mod-97 verification, rather than a generic multi-country IBAN validator. Prefer the unpaid sandbox endpoint POST /v1/sandbox/check-iban-be first for testing; use this paid endpoint ($0.006 USDC) in production flows where a definitive validation is required.

- IBAN is not exactly 16 characters — invalid result
- mod-97 checksum fails — invalid result
- Malformed JSON body — server returns 400 or similar
