ORSF — Slovak business register

Slovak company lookup (IČO/name) via ORSF (Open Register of Slovak Companies) — free, key-free EU coverage.

ORSF (orsf.sk) is a free, normalised JSON REST API over Slovak public company registers (Obchodný register / RPO). Search by name and lookup by IČO (6–8 digits) normalise to the same company-card shape as Brreg, CVR, YTJ and RIK (id, name, address, status, legal form, VAT/IČ DPH, established date, country=SK). Public endpoints are key-free and rate-limited — a useful KYB/AML/supplier-vetting signal for Nordic companies trading in Central Europe.
