Verify a business partner before you invoice them
One IČO is all it takes. FirmAPI checks the company across 38 public registers and shows you the risks in one place – in the browser and via API.
What you learn about a company
The company risk profile is built from official public sources.
Debts and arrears
Debtor lists of the Social Insurance Agency, all three health insurers and the Financial Administration.
Insolvencies and bankruptcies
Bankruptcies, restructurings and debt discharges from the Insolvency Register and the Commercial Bulletin.
Enforcement authorizations
Active enforcement (execution) authorizations from the RPVE register (obcan.justice.sk).
VAT reliability
Tax reliability index, the list of erased VAT payers and VAT ID validation via VIES.
Sanctions lists
Screening against EU and OFAC (US) sanctions lists, including company officers.
Illegal employment
Labour Inspectorate records of illegal employment violations.
Court proceedings
Court decisions where the company appears as claimant or defendant.
Relationships and people
Directors, shareholders and ultimate beneficial owners from the Business Register and the RPVS register.
How it works
In the browser
Enter an IČO or company name in the search and open the company profile. The risk strip at the top instantly shows debts, insolvencies and other risk signals.
Via API
A single GET call returns the full company profile including risk signals as JSON. Ideal for automated KYB checks during customer onboarding.

}Why verify partners
- An unpaid invoice from a bankrupt company is nearly unrecoverable – know the risk in advance.
- VAT liability: trading with an unreliable VAT payer can make you liable for their tax.
- Sanctions screening is a legal obligation for financial institutions and exporters.
- Automated onboarding checks save hours of manual work every month.
