A complete picture of Slovak companies in one API
We aggregate and cross-verify data from dozens of authoritative Slovak and European registers. Below is the full list of fields our REST API returns.
One call, dozens of registers
Instead of scraping ORSR, downloading ZIP files from the Tax Authority and calling the VIES SOAP service, you get all company data in a single HTTP request. Data is refreshed on each source's native cadence – from real-time VAT validation, through daily imports of insolvencies and contracts, to weekly refreshes of RPO.
How to read this list
- Core Core data – available on all plans including the free tier
- Enriched Enriched data – available on paid plans by tier
- Source indicates the authoritative register the field comes from
Registers by group
Each group has its own page describing the registers it holds and the fields we return from them.
Company identification
The basic identity of an entity: who it is, where it is based, since when it exists, who acts on its behalf and what it does. These four registers form the backbone everything else hangs on.
Tax and VAT
Whether a business is registered for VAT decides what goes on the invoice. The answer sits in the Financial Administration registers and, for cross-border trade, in VIES.
Tax Authority registers
The Slovak Tax Authority does not publish one list but a whole set of separate registers. Each has its own file, its own structure and its own publication rhythm. We merge them under one company ID and return them in a single block of the response.
- VAT payer bank accounts
- Excess VAT deductions
- Special VAT scheme (section 68d)
