How this service works
Official Croatian company registry lookup (Sudski registar, court register, daily open-API snapshot). Query: /v1/eu/entreprise/HR/92803032010 (11-digit OIB; 8- or 9-digit MBS accepted). Returns identity (name, short name, form, seat, VAT id HR+OIB, founding date), status with the running procedure, court, capital, main activity (NKD), published e-mails, LEI group and EU funding blocks. Legal persons only: a sole trader (t.p.) or undecided form returns 404, not billed.
Output
Returns a structured record containing: company full name and short name, legal form, registered seat, VAT ID (HR + OIB), founding date, current status including any active procedure (bankruptcy, liquidation, pre-bankruptcy, estates), associated court, share capital, main NKD activity code, publicly listed e-mail addresses, LEI group information, and EU funding blocks.
Example use cases
KYB check on Croatian supplier
“I'm about to sign a contract with a Croatian supplier — their OIB is 92803032010. Can you check the official court register and tell me their legal name, registered address, legal form, founding date, and whether they have any active insolvency or bankruptcy proceedings?”
VAT ID verification for invoicing
“We received an invoice from a Croatian company with OIB 58578437130. Can you look them up in the Sudski registar and confirm their official VAT ID and legal name so I can make sure the invoice details are correct?”
EU funding and LEI research
“I'm researching Croatian companies in the manufacturing sector — can you look up OIB 81505339410 in the Croatian company registry and tell me their main NKD activity, their LEI group affiliation, and any EU funding they've received?”
Technical details
Endpoint
GEThttps://api.sirenic.eu/v1/eu/entreprise/HR/:oib?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, court-register-sourced data on a Croatian company — especially for KYB compliance, supplier due diligence, VAT verification, insolvency checks, or EU funding research. It is more reliable than unofficial Croatian business directories because it draws directly from the Sudski registar daily snapshot and also surfaces LEI and EU funding linkages not available in basic registry UIs.
Side effects
- OIB not found in the registry — company does not exist or number is invalid
- Malformed OIB (not 11 digits) or MBS (not 8-9 digits) returns a validation error
- Daily snapshot lag — very recent registrations or updates may not yet be reflected
- Network/upstream timeout if the Sudski registar data source is temporarily unavailable
- Payment failure (x402) if USDC balance is insufficient
