## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sirenic-croatian-company-registry-lookup-d1c0f433
```

Example prompt: Can you pull the official Croatian court-register record for OIB 92803032010? I need their legal name, registered seat, VAT ID, founding date, current status (any bankruptcy or liquidation proceedings?), and main activity code.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
