How this service works
Czech company lookup in the official ARES register by ICO (company ID) or company name. Returns legal name, status, legal form code, founding date, registered seat address and CZ-NACE activity codes in a schema shared across countries.
Output
Returns a structured JSON object with the queried company's current legal name, normalized status (active/inactive/unknown), legal form code, founding date, registered seat address (street, city, postal code, country code), CZ-NACE activity codes, and the source registry name — all in a schema shared across multiple country endpoints.
Example use cases
Supplier due diligence check
“Before we sign this contract, can you verify that our Czech supplier Škoda Auto a.s. is still an active company in the ARES register and get me their official registered address and legal form?”
ICO number validation for invoicing
“We received an invoice from a Czech company claiming ICO 27082440 — can you check the ARES register to confirm the company name and whether it's currently active?”
Business intelligence on Czech competitors
“I need to know when our Czech competitor was founded, what their official legal form is, and what CZ-NACE industry codes they're registered under — their company name is Avast Software s.r.o.”
Technical details
Endpoint
GEThttps://companies.use.x402atlas.com/cz?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need official Czech company data from the ARES government register — particularly when you have a Czech ICO number or need verified legal status, address, and activity codes for a Czech-registered entity. Prefer this over general web search when you need authoritative, structured registry data for compliance, due diligence, or business verification purposes. The shared output schema makes it easy to combine with sibling endpoints for other countries.
Side effects
- No match found for the given ICO or company name — returns count:0 with a note
- Ambiguous company name returns multiple results — agent must disambiguate
- Invalid or malformed ICO returns an error or zero results
- ARES registry temporarily unavailable — upstream timeout or service error
- Query string too long (exceeds 200 characters) — rejected by schema validation
