ARES Scraper - Czech Republic Company Registry Data
Pricing
Pay per usage
Scrape Czech company data from ARES (Administrativni registr ekonomickych subjektu). Search by company name or ICO number. Extract registration details, addresses, NACE codes, VAT numbers, and legal forms. Official Ministry of Finance API, no login required.
Search for companies by name. Czech diacritics are supported (e.g., 'skoda', 'ceska posta'). The ARES API rejects queries returning more than 1,000 results — use specific terms or combine with filters below.
Look up one or more companies by their 8-digit ICO number. Separate multiple ICOs with commas (e.g., '00177041, 25820524'). When set, this takes priority — the actor fetches each company directly.
Filter results to a specific city (e.g., 'Praha', 'Brno', 'Ostrava'). Applied after search, so the search query must still return fewer than 1,000 total results.
Filter by legal form code. Applied server-side via the ARES API.
Filter by economic activity code (e.g., '6201' for software development, '4711' for retail). See https://www.czso.cz/csu/czso/klasifikace_ekonomickych_cinnosti_cz_nace for codes.
When enabled, dissolved or inactive companies are excluded from results.
Maximum number of companies to return. The ARES API allows up to 1,000 results per search query.
