How this service works
Call when an agent needs whether an IBAN is a mod-97-valid GL number of length 18. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/check-iban-gl first.
Output
A boolean or structured result indicating whether the submitted string is a valid Greenlandic (GL) IBAN: correct country code prefix 'GL', exactly 18 characters in length, and passing the mod-97 checksum algorithm.
Example use cases
Pre-payment IBAN sanity check
“Before we wire funds to this Greenlandic supplier, can you verify that their bank account 'GL8964710001234564' is a legitimate GL IBAN that passes the mod-97 check?”
Onboarding form IBAN validation
“A user just entered 'GL1234500000012340' as their bank account number — can you confirm whether that's a valid Greenlandic IBAN before we save it to their profile?”
Batch payout data quality check
“We have this IBAN from our payout list: 'GL5000400440116243' — is it a properly formatted and mod-97-valid GL account number so we know it won't get rejected?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-gl?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate a Greenlandic (GL) IBAN and require mod-97 checksum verification along with the 18-character length constraint. If a free sandbox endpoint (/v1/sandbox/check-iban-gl) is available, prefer that to avoid the $0.006 USDC cost. Choose country-specific IBAN validators (like this GL one) over generic IBAN validators when you need precise country-code and length enforcement for Greenland.
Side effects
- Input string is empty or exceeds 20000 characters — request rejected
- IBAN has correct GL prefix but wrong length — returns invalid
- Mod-97 checksum fails — returns invalid with failure reason
- Non-GL IBAN submitted — may return invalid due to wrong country code
- Network or payment authorization failure — HTTP 402 or 5xx error
