Czech Republic Company Check (identification number) — KYB MCP

Czech Republic Company Check (identification number)

Check companies in Czech Republic by their identification number (IČO) in one call and get a clean English JSON answer with red flags, source attribution and a date on every field. Built for AI agents (MCP) and for KYB / AML onboarding, counterparty and supplier due diligence, vendor risk and compliance checks.

• One number → one answer from official open registers plus GLEIF Global LEI Index: Level 1 (LEI-CDF), Level 2 (RR-CDF), Reporting Exceptions and Official sanctions lists: US OFAC (SDN and Consolidated non-SDN), EU consolidated financial sanctions (FSF), UK Sanctions List (FCDO) — legal entities only.
• One schema for every country: the same fields and flags whether you check one Czech Republic company or a thousand — your agent parses one format.
• Agent-ready: an MCP server (Streamable HTTP, /mcp) with check_company, check_companies and list_sources, a plain GET /check?country=&id= endpoint, and classic batch runs (list of numbers → dataset).
• Change history: registers publish only the current state; we keep our own snapshots, so every answer shows what was added or removed since history_since (e.g. a status change or a new sanctions listing).
• Pay per check (one charge per company answered; the price is on the Pricing tab), no subscription. Malformed numbers, sole traders and individuals are not charged. In Standby (MCP / HTTP) mode Apify also bills the small platform usage of the server run, as for every Standby Actor. Set a maximum cost per run in Apify to cap spending: when it is reached, the Actor returns an error instead of data.

What we check

Source	Licence	Publisher updates
Business Register of the Czech Statistical Office (Registr ekonomických subjektů, RES): legal entities, legal form, dates of establishment and dissolution, activity (CZ-NACE), size band (CZ)	Several, see Data licences	weekly
Insolvent employers registered by the Labour Office of the Czech Republic (moratoria and insolvency petitions with open wage-claim periods, last ~5.5 months) (CZ)	Open data of MPSV and ÚP ČR: no copyrighted works, no database rights, free re-use	daily
GLEIF Global LEI Index: Level 1 (LEI-CDF), Level 2 (RR-CDF), Reporting Exceptions	CC0 1.0	daily
Official sanctions lists: US OFAC (SDN and Consolidated non-SDN), EU consolidated financial sanctions (FSF), UK Sanctions List (FCDO) — legal entities only	Several, see Data licences	daily

Data refreshed at least weekly; every field carries its source date (provenance), and every answer lists each source with the date it was loaded (sources[].loaded_at; list_sources is free).

flags — true is a red flag: not_found (the number is not in the register dump), not_active, insolvency, liquidation, sanctions (match by registration number or LEI), sanctions_name_match (same name, same country: verify manually). false means there is no record in the loaded snapshot — it is not a clean bill of health. null means unknown. Call list_sources (free) for load times.

Czech Republic: The ČSÚ open register (RES) lists all live legal entities and those dissolved within the last four years; entities dissolved earlier are dropped, so an unknown code is unknown, not fictitious. Sole traders and other natural persons are not supported. A valid identification number without a record therefore returns not_found: null (unknown, not fictitious) and is not charged.

Not affiliated with or endorsed by the Czech Statistical Office (ČSÚ), the Ministry of Labour and Social Affairs or the Labour Office of the Czech Republic. Data from RES, the Business Register of ČSÚ (snapshot as of the 15th and the end of each month), and the Labour Office list of insolvent employers. Status: a dissolution date → dissolved (with the manner of dissolution); a live entity whose name carries the statutory suffix "v likvidaci" → in_liquidation; otherwise active. flags.insolvency is true only when the Labour Office lists an insolvency petition or moratorium against the entity as an employer within the last ~5.5 months; otherwise it is null (unknown), because there is no open bulk copy of the insolvency register (ISIR). Partnerships whose names contain a partner's name are legal entities and are returned like any company.

Identifiers

Country	Identifier	Format	Example
Czech Republic (CZ)	identification number (IČO)	8 digits, leading zeros may be omitted; a CZ prefix (Czech VAT number of a legal entity = CZ + IČO) is accepted	00177041

Spaces, dashes and a country prefix are accepted. Legal entities only: sole traders and other natural persons are not supported, not stored and not charged. No data about people (officers, owners, contacts) is ever returned; addresses are city level only.
