How this service works
Call when an agent needs whether an IBAN is a mod-97-valid SC number of length 31. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/check-iban-sc first.
Output
A boolean or structured result indicating whether the provided IBAN passes the mod-97 checksum algorithm and meets the 31-character SC (Swiss) IBAN length requirement, potentially with details on which check failed if invalid.
Example use cases
Pre-payment IBAN sanity check
“Before I wire the invoice payment, check whether the IBAN CH9300762011623852957 my supplier sent me is a valid mod-97 Swiss account number of the right length.”
Onboarding bank account verification
“A new user just entered their Swiss bank account IBAN CH5604835012345678009 — can you verify it passes mod-97 validation and is correctly 31 digits before we save it?”
Bulk payout data quality gate
“I'm about to process payouts and need to confirm that IBAN CH2989144532982975493 is a structurally valid Swiss IBAN before queuing it — does it pass the checksum and length checks?”

Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-sc?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate a Swiss (SC-prefixed) IBAN for mod-97 checksum correctness and 31-character length conformance — ideal before initiating payments, during financial onboarding, or as a data quality gate. Prefer the free sandbox POST /v1/sandbox/check-iban-sc for testing. Choose this over generic IBAN libraries when you need a reliable, paid, hosted microservice with no local dependency.
Side effects
- IBAN string is empty or missing — request rejected

- Non-Swiss or wrong-country-prefix IBAN provided — may return invalid or unsupported
- Malformed input schema — 400-level error
- Payment of $0.006 USDC not included or rejected — 402 Payment Required
