How this service works
Call when an agent needs whether an IBAN is a mod-97-valid VA number of length 22. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/check-iban-va first.
Output
Returns whether the submitted IBAN string is a valid Virtual Account number — specifically confirming it is exactly 22 characters long and passes the mod-97 checksum algorithm used in IBAN validation.
Example use cases
Payment routing IBAN pre-check
“Before we initiate this payment, can you verify that 'DE89370400440532013000' is a mod-97-valid Virtual Account IBAN of exactly 22 characters?”
Bulk onboarding data cleanup
“I'm cleaning up our customer bank records — can you check if the IBAN 'NL91ABNA0417164300' passes mod-97 and is a valid 22-character VA number?”
Finance form submission validation
“A user just submitted 'FR7630006000011234567890189' as their virtual account IBAN — can you confirm it's exactly 22 characters long and passes mod-97 before we save it?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-va?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, rule-based check that a specific IBAN both conforms to the 22-character Virtual Account length constraint AND passes the standard mod-97 checksum — without needing a live bank lookup or registry verification. Prefer the free sandbox endpoint (/v1/sandbox/check-iban-va) for testing; use this paid endpoint in production flows where reliability matters.
Side effects
- IBAN string shorter or longer than 22 characters returns invalid result
- Input string contains non-alphanumeric characters causing parse failure
- Mod-97 check fails for IBANs with incorrect check digits
- Empty or missing value field causes a request validation error
- Malformed JSON body may result in a 400 Bad Request
