What data we provide

A complete picture of Slovak companies in one API

We aggregate and cross-verify data from more than fifteen authoritative Slovak and European registers. Below is the full list of fields our REST API returns.

One call, more than fifteen 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.
