How this service works
Call when an agent needs whether an IBAN is a mod-97-valid GI number of length 23. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/check-iban-gi first.
Output
Returns a boolean or structured result indicating whether the provided string is a valid Gibraltar IBAN: passes mod-97 checksum, starts with the 'GI' country code, and is exactly 23 characters in length.
Example use cases
Payment form bank account validation
“Before we process this international wire, can you verify that GI75NWBK000000007099453 is a properly formatted and mod-97-valid Gibraltar IBAN?”
KYC onboarding IBAN check
“We're onboarding a new customer who provided the IBAN GI12ABBY11223344556677 — can you confirm it's a valid Gibraltar IBAN before we proceed?”
Batch reconciliation pre-check
“I have a Gibraltar account number GI62BARC20000055779911 that needs to go into our ledger — please validate it passes the mod-97 test and is exactly 23 characters.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-gi?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate a Gibraltar (GI) IBAN against the mod-97 algorithm and the exact 23-character GI format. Prefer the free sandbox endpoint (POST /v1/sandbox/check-iban-gi) for testing. Use this paid endpoint in production workflows where confirmed validation is required. For other IBAN country codes (LT, LU, LV, MK, MR, PK, etc.), use the corresponding country-specific sibling endpoints.

- String does not start with 'GI' country code — returns invalid
- Empty or null input — returns error or invalid
- Network or upstream service error — HTTP 5xx
- Payment not included or insufficient — HTTP 402
