# Czechia — ARES Lookup

**Live, direct-to-government access to Administrativní registr ekonomických subjektů (ARES) — Czech Ministry of Finance.**

> Single-country variant of the cross-border [Cross-Border UBO Chain Walker](../ubo-cross-border-chain-walker/SKILL.md). Use this skill when the user is explicitly focused on **Czechia**.

## What you get

- **Direct query to ARES.** Every tool call hits Administrativní registr ekonomických subjektů (ARES) — Czech Ministry of Finance at the moment you ask. No nightly scrape, no aggregator middle layer.
- **Unmodified responses.** Field names, status codes, and (where available) raw filing bytes are returned exactly as the registry's own system emits them.
- **Native ID format support.** 8-digit IČO (e.g. `45274649` for ČEZ a.s.).
- **Sample entity:** ČEZ a.s..

## Available tools (jurisdiction = `CZ`)

`search_companies`, `get_company_profile`, `get_officers`, `get_shareholders`, `get_charges`, `get_code_description`, `get_specialised_record`, `search_specialised_records`, `search_addresses`, `list_change_batches`

For every tool, pass `jurisdiction: "CZ"` (case-insensitive).

## Example prompts

```
Find ČEZ a.s. in ARES and pull current statutory body
```

```
Search ARES for all Czech political parties registered after 2020
```

```
Look up the Czech address `Václavské náměstí, Praha 1` and list registered businesses there
```

## Workflow

### Step 1 — Resolve the entity
```
search_companies({ jurisdiction: "CZ", query: "<name or ID>" })
get_company_profile({ jurisdiction: "CZ", company_id: "<id>" })
```

### Step 2 — Pull the relevant register slice
Pick from the available tools list above. For UBO walks across borders, return to the [Cross-Border UBO Chain Walker](../ubo-cross-border-chain-walker/SKILL.md).

## Quirks specific to Czechia

- ARES is the umbrella over multiple Czech registers: Obchodní rejstřík (companies), RŽP (trades), RPSH (political parties), RES (statistical), RUIAN (addresses).
- Czech UBO register (Evidence skutečných majitelů) is publicly accessible — UBO support is on the roadmap.
- **Specialised records**: `search_specialised_records({source:"rpsh"})` for political parties; addresses via `search_addresses`. These are unique to ARES coverage.
- Multiple registers means a single legal entity may appear under different IDs across them — `get_code_description` decodes the registry codes.

## Provenance

- **Government URL**: <https://ares.gov.cz/>
