Czech business register (ARES) — look up any Czech company or sole trader by IČO or by name, from the Ministry of Finance’s official register of economic subjects.

Tools

• ares_lookup_ico({ ico }) — one economic subject by its 8-digit IČO: registered trading name, legal form, seat address, founding date, dissolution date, DIČ (VAT) number, CZ-NACE activity codes.
• ares_search_name({ name, limit, offset, onlyActive }) — subjects whose trading name matches, with the total match count so a precise hit is distinguishable from a common word.

Auth

Keyless. No registration, no header, no quota documented.

Data sources

• https://ares.gov.cz/ekonomicke-subjekty-v-be/rest/ekonomicke-subjekty/{ico} — one subject by IČO.
• https://ares.gov.cz/ekonomicke-subjekty-v-be/rest/ekonomicke-subjekty/vyhledat — POST search, returns pocetCelkem (total) plus a page of subjects.

ARES is the Ministry of Finance’s consolidated view over the commercial register (OR), the trade register (RŽP), the statistical register (RES) and the VAT payer register — so one IČO answers questions that would otherwise need three lookups.

Traps

• IČO must be zero-padded to 8 digits on the REST path. “177041” 404s, “00177041” resolves; the pack pads for you.
• A dissolved company still resolves. active is derived from whether datumZaniku is present, not from the lookup succeeding — treating a 200 as “still trading” is wrong.
• pocet (page size) caps at 200 and a larger value is a 400, so the pack clamps instead of passing through.
• Field names in raw stay Czech on purpose; the mapped fields are renamed to English so a caller does not need to know obchodniJmeno is the trading name.

Tools

• ares_lookup_ico — One Czech company or sole trader, by IČO, from the official ARES register.
• ares_search_name — Czech companies matching a name, with their IČO, from the official ARES register.
