❓ Frequently Asked Questions

Is it legal to scrape ARES / ares.gov.cz? This Actor reads only the official open data that the Czech Ministry of Finance publishes via its public ARES REST API — no login or circumvention involved. As with any registry data, credit the source (ARES / ares.gov.cz) and follow ARES's terms and applicable law such as GDPR for your specific use case.

Does ARES have a public API? Yes. The Czech Ministry of Finance publishes ARES as a fully open, free REST API (ares.gov.cz/ekonomicke-subjekty-v-be) — no key, no login, no signup. This Actor is a friendly, filterable export layer on top of it: set filters in a form, run, and download a clean dataset with pagination handled and nested fields flattened into columns.

Is this an ARES API alternative for bulk download? Yes — it's the easiest ARES API alternative for non-developers: no code, automatic pagination within the ARES query window, nested JSON flattened to spreadsheet columns, de-duplication by IČO, and direct export to CSV / Excel / JSON.

Do I need an API key or a login? No. There is no ARES account, login or API key required — only an Apify account. The Actor pulls publicly available registry records over direct HTTP.

How do I export Czech company data to CSV or JSON? Every run writes one row per company to a dataset you can export as CSV, JSON, Excel or XML from the Apify console or via the Apify API. Set your filters, run, and use the Export button to download an .xlsx / .csv of the whole Czech company segment.

How many companies can I get per query? ARES caps each search at 1,000 results. If your filters match more, the API refuses the query — the Actor logs a clear "narrow your filters" warning and stops gracefully. To cover a larger segment, split your run by municipality, legal form, NACE code or postcode and combine the datasets.

Does it include company emails and phone numbers?

No — the ARES public search returns official registry fields (IČO, VAT, legal form, address, dates, NACE), which do not include email or phone. For contact enrichment, combine the IČO / company list this Actor produces with a separate email-finding step.

How do I get a list of IT companies in Prague from ARES?

Set czNace to 6201 (computer programming) and kodObce to 554782 (Praha), then run. The Actor returns every matching Czech IT company with IČO, VAT, address and NACE, ready to export.

How do I look up a Czech company by IČO?

Enter one or several comma-separated 8-digit IČO numbers in the ico field. The Actor pulls the official ARES record for each, including VAT, legal form, address and active status.
