ARES Scraper: Czech Company Registry & IČO Lookup

Search Czech companies in the official ARES register by name, ICO, city, NACE code, legal form or founding date: VAT ID, address, NACE, employee band. $1.50 per 1,000 companies.

ARES, run by the Czech Ministry of Finance, joins the commercial register, the trade licence register, the statistical register (RES) and the VAT register into one record per company. It is the official starting point for any Czech B2B list or company check.

Quick start

1. Press Start. The form is already filled with this example input, so the first run returns real rows in under a minute:

{
  "searchTerms": [
    "software"
  ],
  "cities": [
    "Brno"
  ],
  "maxResults": 20
}

2. Swap in your own values, or call the Actor through the Apify API, Make, Zapier, n8n or the Python/JS clients with the same JSON.
3. Download the results as JSON, CSV or Excel from the Output tab, or schedule the run to repeat.

FAQ

Where does the data come from? From the official ARES REST API of the Czech Ministry of Finance (ares.gov.cz), free to use without registration.

Is any personal data included? Natural persons (sole traders, self-employed farmers and foreign individuals doing business) are never requested or output, and no data about people (statutory bodies, shareholders, owners) is collected. Every row is a legal entity.

How fresh is it? Live. ARES reflects the source registers within a day.

Can I get only new records each day? Yes. Use the date window input and schedule the Actor; each run returns what is new in that window.
