Czech Company Check (ARES)

Check that a Czech counterparty exists and is active before you onboard, pay or sign. Input IČO numbers (or name + optional town); get one structured record per company.

Use it for: KYB/onboarding, supplier and vendor checks, invoice/VAT (DIČ) verification, AI agents that need to confirm a Czech entity. Not for building lead or marketing lists.

Input

{ "queries": ["27082440", "Škoda Auto"], "includePersons": false }

Output (per company)

ico, dic, legalName, status (active/dissolved), legalForm, registeredAddress, dateEstablished, czNace[], registryCourt, fileNumber, persons[] (only if includePersons), source, retrievedAt, matchNote.

Pricing

First 25 company results free per account, then $0.03 per company found. Lookups that find nothing are free.

Data source

Data from ARES (Administrativní registr ekonomických subjektů), operated by the Ministry of Finance of the Czech Republic: https://ares.gov.cz. Used under the ARES service conditions (https://data.mf.gov.cz/api/ares.html); requests are rate-limited and cached to respect them.

Using from AI agents / Apify MCP

AI agents can call this Actor through the Apify MCP server at https://mcp.apify.com: find it with search-actors and run it with call-actor, or load it as its own tool with https://mcp.apify.com?tools=fieldnoteagents/czech-company-check-ares. Example input: {"queries": ["27082440"], "includePersons": false}.

• Max charge per run must be at least $0.05. If you set maxTotalChargeUsd (in callOptions) below $0.05, the run is refused before it starts. $0.05 or more is fine; the Actor stops cleanly at your limit.
• The first 25 company results per Apify account are free, then $0.03 per company found. Lookups that find nothing are free.
• call-actor returns the run and dataset IDs; read the results with get-dataset-items.

Data protection (GDPR)

Some records include names of directors, board members or shareholders. These are personal data under GDPR. Use them only for a lawful purpose such as KYB, AML/KYC, supplier due diligence or credit checks, not for marketing lists or unsolicited outreach. You are the controller for what you do with the output. Set includePersons: false to drop personal names entirely.
