How this service works
Call when an agent needs whether an IBAN is a mod-97-valid TN number of length 24. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/check-iban-tn first.
Output
Returns a boolean or structured response indicating whether the supplied string is a valid Tunisian (TN) IBAN — exactly 24 characters, correct country prefix, and passing the ISO 7064 mod-97-10 checksum calculation.
Example use cases
Pre-payment IBAN sanity check
“Before I wire money to my Tunisian supplier, can you verify that TN5904018104004942712345 is a valid TN IBAN — correct length and mod-97 checksum?”
Batch onboarding data quality
“A new vendor filled in their Tunisian bank details as TN1400400174401003000526 — can you check if that IBAN is structurally valid before we save it to our system?”
Customer support IBAN dispute
“A customer is claiming their payment failed because of a bad IBAN. Their account number is TN5910006035183598478831 — can you tell me if it's actually a properly formatted Tunisian IBAN?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-tn?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate a Tunisian (TN) IBAN against both the 24-character length constraint and the mod-97 checksum. Prefer the sandbox endpoint (POST /v1/sandbox/check-iban-tn) during development to avoid the $0.01 USDC fee. Choose this over generic IBAN validators when you need country-specific enforcement for TN format only.
Side effects
- Input string is empty or missing — validation cannot proceed
- IBAN length is not 24 characters — fails length check before mod-97
- Country code prefix is not 'TN' — wrong country validator called
- Mod-97 remainder is not 1 — checksum invalid
- Network or upstream error returns non-200 response
- Payment not attached or insufficient — x402 payment required error
