How this service works
Call when an agent needs whether an IBAN is a mod-97-valid CR number of length 22. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/check-iban-cr first.
Output
Returns a boolean or structured result indicating whether the provided string is a valid Costa Rican (CR) IBAN: passes the ISO 7064 mod-97-10 checksum algorithm and is exactly 22 characters in length, consistent with the CR IBAN standard.
Example use cases
Pre-payment IBAN verification
“Before I send this wire transfer to CR05015202001026284066, can you confirm it's a legitimate Costa Rican IBAN by checking the mod-97 checksum and length?”
Batch onboarding data quality check
“I'm onboarding a new Costa Rican supplier and they gave me the bank account IBAN CR72015109810010123456 — can you verify that's a valid CR IBAN before I add it to our payment system?”
Form validation before submission
“A user just entered CR05015202001026284066 as their Costa Rica bank IBAN in our checkout form — check whether it's mod-97 valid and exactly 22 characters so I know if I should flag an error.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-cr?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, algorithmic check of a Costa Rican IBAN's structural validity (mod-97 checksum + 22-character length) without relying on a bank lookup or live registry. Prefer the free sandbox endpoint (/v1/sandbox/check-iban-cr) for development and testing before committing to the $0.01 USDC paid call.
Side effects
- Input string is empty or missing — validation error returned
- IBAN too short or too long (not 22 characters) — fails length check
- Country code is not CR — may fail or return invalid for non-CR IBANs
- Mod-97 checksum does not match — returns invalid
- Malformed input with non-alphanumeric characters — parsing error
- Payment failure (x402) if USDC balance is insufficient
