ARES is the Czech Ministry of Finance's register of economic subjects. It joins the base register of subjects with the commercial register, the statistical register, the trade licence register and the VAT register. One run builds a company list: choose the legal form (for example s.r.o. or a.s.), the activity codes, a city or region, and whether you want active or ceased subjects, and you get one clean row per company with the IČO, VAT ID, address, tax office, founding date and activities.

How much does Czech ARES Scraper cost?

Companies	This actor	Most used Czech ARES actors on the Store
1,000	$1.00	$2.50 to $3.50
10,000	$10.00	$25 to $35
100,000	$100.00	$250 to $350

Plus $0.001 per run. A weekly run of 300 new companies from one city costs about $0.30 a week, or about $1.30 a month.

Why people switch

• One flat price. Compute is included, so the bill follows the number of companies and nothing else.
• Searches that go past 1,000. ARES refuses any search that matches more than 1,000 subjects. This actor cuts a broad search into smaller ones by legal form, tax office and activity code, reads each part, and removes repeats, so a request for tens of thousands of companies works.
• Filters ARES does not offer. Region, status and founding date are applied to the rows, and activity codes bring the codes below them, which ARES matches only one level at a time.
• Clean rows. 37 fields: legal form in words and as a code, activity codes with Czech names, address parts, tax office, VAT payer flag and the registers a company is active in.

How to use Czech ARES Scraper

1. Open the actor and press Start. The default input returns 50 active limited liability companies (s.r.o.) in Mladá Boleslav.
2. Or paste this input, which lists software companies in Brno that were founded since 2020:

{ "legalForms": ["112", "121"], "cities": ["Brno"], "activityCodes": ["6210"], "foundedFrom": "2020-01-01", "maxItems": 500 }

3. Download the results as JSON, CSV or Excel, or read them through the API.

Use it from code

curl -X POST "https://api.apify.com/v2/acts/one_dollar_store~czech-ares-companies-scraper/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"legalForms": ["112"], "cities": ["Brno"], "maxItems": 100}'

from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("one_dollar_store/czech-ares-companies-scraper").call(
    run_input={"legalForms": ["112"], "cities": ["Brno"], "maxItems": 100}
)
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item["ico"], item["name"], item.get("vatId"), item["municipality"])

Use it from an AI assistant

Claude, ChatGPT, Cursor and other assistants can call this actor through Apify's MCP server. Add it with this server address:

https://mcp.apify.com?tools=one_dollar_store/czech-ares-companies-scraper

Then ask, for example: "List 100 active Czech joint-stock companies in the Moravian-Silesian region with their IČO and VAT ID."

Switching from another ARES actor

Most ARES actors take an IČO or a name. Here the main inputs are legalForms, activityCodes, cities, regions, nameWords, status, foundedFrom and maxItems. The core output fields are ico, name, vatId, legalForm, address, municipality, foundedDate and status.

Input

All filters are optional and combine with AND. For lists, one match is enough.

legalForms	list	all except sole traders	Legal form codes such as 112 (s.r.o.), 121 (a.s.), 111 (v.o.s.), 205 (družstvo), 706 (spolek).

activityCodes	list of text	none	CZ-NACE 2025 codes, 2 to 5 digits, such as 6210 for software or 4711 for retail. Codes below each one are added.
includeSubCodes	true or false	true	Add the codes below the ones you typed. Turn off to match only the exact codes.

  "legalForms": ["112"],
  "regions": ["Jihomoravský kraj"],
  "activityCodes": ["4711", "4719"],
  "status": "active",
  "foundedFrom": "2023-01-01",
  "maxItems": 2000
}

Limits

• ARES refuses searches over 1,000 matches. The actor cuts a broad search by legal form, then by tax office, and as a last step by activity code, and reads each small part. If a part still holds more than 1,000 companies it is skipped, and the run summary says so in coverageNote. The last step can miss companies that list no activity code. Adding a city, a legal form or activity codes gives a complete list.
• Region, status and founding date are checked on the rows. ARES cannot search by them, so they do not make a run faster. The region filter reads the tax office areas of the region and then checks each address, so a few companies that report to an office in another region can be missed.
• Name search is by whole words. It ignores case and accents, and a part of a word does not match.
• Activity codes are the 2025 edition. Codes from the 2008 list, such as 62010, do not match. The old codes are returned in activityCodes2008 for reference.
• Status. Active and ceased come from the base register (ROS). When a subject has no ROS entry, as many sole traders do, the other registers decide. A company in liquidation (v likvidaci) is still active until it is deleted.
• What ARES does not hold. The record has no phone, email, website, employee count or turnover. Names of activities and legal forms are in Czech.
• Sole traders. Their rows come without the tax number, street, house number, postal code and full address. The registered name of a sole trader is the person's own name.
• Pace. The actor sends at most 4 requests a second and stops a run after 4,000 requests. Runs stop cleanly before the run time limit with the rows delivered; raise Timeout under Run options for very large lists. A run returns up to 100,000 companies.

FAQ

What is the cheapest Czech ARES scraper on Apify? This actor costs $1 per 1,000 companies with platform usage included. The four most used Czech ARES actors on the Store charged $2.50 to $3.50 per 1,000 when we checked on 27 October 2026.

How much does it cost to scrape 10,000 Czech companies? $10, plus $0.001 for each run.

Do I pay for compute or proxy on top? No. The price covers platform usage, and the actor needs no proxy because it reads the official ARES API.

Does it need an API key? No.

Why do I get fewer companies than I expected? ARES will not return a search that matches more than 1,000 subjects. The actor cuts such searches into parts, but a part that is still too broad is skipped. Look at coverageNote in the run summary, and add a city, legal form or activity code.

How do I find new companies? Set foundedFrom and add a city, region or legal form so the run reads only that part of the register. The founding date is checked on each row, so a search with no other filter reads many old companies first.

Is it legal? ARES is public register data from the Czech Ministry of Finance. The ministry says anyone may use its services if they respect the operating conditions, that it may restrict users who send more than 500 queries a minute, and that the information is for information only. It states no licence for reuse. The actor reads the public API at no more than 4 requests a second, and the ministry's robots.txt only disallows /cms/, which the API is not under. Sole traders are in the register; the actor removes their tax number, which can be a personal number, and their street address, but the name of a sole trader is the person's own name. You are responsible for how you use the data, including GDPR and the rules on commercial messages.

Is this an official ARES product? No. It is an independent tool and is not affiliated with or endorsed by the Czech Ministry of Finance.

Do I need an Apify account? Yes. Actors run from an Apify account, and a free account is enough to start: it includes $5 of platform usage every month. You can sign up here. This is a referral link and it costs you nothing.

Is there a limit on the free plan? Yes. A run started from a free plan account delivers the first 10 results, then ends with a message and a link to the plans. Any paid plan returns everything you ask for, up to your own limit. The price per result is the same on every plan.
