How this service works
Call when an agent needs whether an IBAN is a mod-97-valid BG number of length 22. Exact $0.001 USDC. Prefer unpaid POST /v1/sandbox/check-iban-bg first.
Output
Returns a boolean or structured result indicating whether the supplied string is a valid Bulgarian IBAN — specifically confirming that it starts with the BG country code, is exactly 22 characters long, and passes the ISO 7064 mod-97 checksum algorithm.
Example use cases
Pre-payment IBAN sanity check
“Before I wire money to a Bulgarian supplier, can you validate that this IBAN is properly formatted and passes the mod-97 check: BG18RZBB91550123456789?”
Onboarding form bank account verification
“A new user just entered their Bulgarian bank account IBAN in our onboarding form — can you verify it's a legitimate BG IBAN with the right length and checksum? The value is BG80BNBG96611020345678.”
Bulk payment file validation
“I'm about to process a payment batch and one of the recipient IBANs looks off — it says BG72TTBB94550123456789. Can you confirm whether it's a valid Bulgarian IBAN?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-iban-bg?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to validate a Bulgarian (BG) IBAN against both the correct length (22 characters) and the mod-97 checksum. Prefer the unpaid sandbox endpoint POST /v1/sandbox/check-iban-bg for testing. Choose this over generic IBAN libraries when you need a lightweight, hosted, API-accessible check without deploying your own code, especially inside an automated agentic workflow.
Side effects
- Input string is empty or missing — validation error returned
- IBAN is not 22 characters — fails length check
- Country code is not BG — fails country check
- Mod-97 checksum does not equal 1 — fails checksum validation
- Malformed input with non-alphanumeric characters — may return error or false
- Payment of $0.001 USDC not received — request rejected with 402
