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 JSON object with the echoed query, country code (CZ), registry name (ARES), match count, and an array of matched companies each containing: current legal name, registration number, normalized status (active/inactive/unknown), legal form code, founding date, registered seat address (street, postal code, city, country code), CZ-NACE activity codes, and website field.
Example use cases
Supplier due diligence check
“I need to verify a potential Czech supplier — their company ID is 27082440. Can you pull their details from the official ARES register, including whether they're still active, their registered address, and founding date?”
Company name to registry details
“I only have the name 'Škoda Auto' — can you search the Czech ARES register and get me their ICO number, legal form, registered seat address, and business activity codes?”
Invoice validation for Czech counterparty
“We received an invoice from a company claiming ICO 45274649. Can you check the Czech ARES register to confirm their official legal name and whether they're currently an active entity?”

Endpoint
GEThttps://companies.use.x402atlas.com/czech-company-data?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to look up Czech companies in the official ARES register, either by their ICO (company ID) or name. It returns normalized, structured data using a cross-country schema, making it ideal for supplier verification, due diligence, invoice validation, or enriching business records with official Czech registry data. Prefer this over generic web search when authoritative legal entity data is required.
Side effects
- Zero results returned if ICO or name does not match any ARES record
- Partial or ambiguous name queries may return multiple companies requiring disambiguation
- ARES registry may occasionally be unavailable causing timeout or error response
- Inactive or dissolved companies may have incomplete address or activity data
- Non-Czech company IDs will not match and return zero results
