How this service works
Call when an agent needs whether an IBAN is a mod-97-valid SM number of length 27. Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/check-iban-sm first.
Output
Returns a boolean or structured result indicating whether the submitted string is a valid San Marino (SM) IBAN: 27 characters long, starts with 'SM', and passes the mod-97 checksum algorithm.
Example use cases
Payment form IBAN pre-validation
“Before we process this wire transfer, check if SM86U0322509800000000270100 is a valid San Marino IBAN so we don't reject it downstream.”
Bulk onboarding data quality check
“A new customer entered SM12A0503219200000000012345 as their bank account — can you verify it's a properly formatted San Marino IBAN with a valid mod-97 checksum?”
Compliance screening for SM accounts
“Our compliance workflow needs to confirm that SM76P0854009812123456789012 is a legitimate San Marino IBAN before we whitelist it — please validate it.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-sm?utm_source=zero.xyzWhen to prefer
Use this endpoint specifically when you need to validate an IBAN that begins with the country code 'SM' (San Marino) and should be exactly 27 characters long. Prefer the free sandbox endpoint POST /v1/sandbox/check-iban-sm for testing. For other country IBANs, use the corresponding country-specific sibling endpoints on the same host.

- Non-string or malformed JSON body causes a 400-level error
- Payment of exact $0.007 USDC required; insufficient payment returns a 402 response
