## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## 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](https://data.gov.cz/datová-sada?iri=https://data.gov.cz/zdroj/datové-sady/00025593/7bad26fdd8554ce715b81b5b416d75f0) (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)](https://data.mpsv.cz/web/data/insolventni-zamestnavatele-evidovani-uradem-prace-cr) (CZ) | [Open data of MPSV and ÚP ČR: no copyrighted works, no database rights, free re-use](https://data.mpsv.cz/web/data/podminky-uziti) | daily |
| [GLEIF Global LEI Index: Level 1 (LEI-CDF), Level 2 (RR-CDF), Reporting Exceptions](https://goldencopy.gleif.org/api/v2/golden-copies/publishes/latest) | [CC0 1.0](https://www.gleif.org/en/meta/lei-data-terms-of-use) | daily |
| [Official sanctions lists: US OFAC (SDN and Consolidated non-SDN), EU consolidated financial sanctions (FSF), UK Sanctions List (FCDO) — legal entities only](https://sanctionslistservice.ofac.treas.gov/api/PublicationPreview/exports/SDN.XML) | 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.

### Input

```json
{
  "country": "CZ",
  "ids": [
    "00177041"
  ]
}
```

Up to 10,000 numbers per run.

### Use from an AI agent (MCP)

Add the Actor as a remote MCP server: `https://kyb-data--czech-republic-company-check.apify.actor/mcp` with your Apify token,
or through `mcp.apify.com`. Tools: `check_company(company_id, country)`, `check_companies(company_ids, country)`
(up to 50), `list_sources()`.

### Data licences

All data comes from official open sources under open licences; attribution (title, dataset URL, licence,
`loaded_at`) is included in the `sources` field of every answer.

## MCP server setup

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
