How to call it

The same tool through each route. MCP clients reach it through Strale’s server at https://api.strale.io/mcp; the call below is what the agent sends.

# Needs an API key. max_price_cents caps what this call may cost.
curl -X POST https://api.strale.io/v1/do \
  -H "Authorization: Bearer $STRALE_API_KEY" \
  -H 'Content-Type: application/json' \
  -d '{
    "capability_slug": "cz-company-data",
    "inputs": {
      "ico": "00177041"
    },
    "max_price_cents": 5
  }'

const strale = new Strale({ apiKey: process.env.STRALE_API_KEY! });

Limitations

• Official registry data access

  Data comes from the Czech Ministry of Finance's ARES public API, reused under the ARES operating conditions and Czech open-data law (https://ares.gov.cz/stranky/open-data). Results name ARES as their source. ARES data is informative only and is not an official document.

• Registry status interpretation

  Liquidation reflects a current VR liquidator appointment, while insolvency reflects an active IR registration rather than a bankruptcy ruling. Status is unknown when an expected VR record is unavailable; ROS active status alone cannot exclude liquidation.

• Natural persons' DIČ not derivable

  DIČ is returned verbatim when ARES has it. For natural persons registered as entrepreneurs, the DIČ may be CZ + rodné číslo and cannot be derived from IČO alone.

• Fuzzy name search returns first match only

  Name search returns only the first ARES match. Ambiguous names can resolve to the wrong entity.

  What to do instead: Pass IČO directly when known.

• Sole proprietors with only trade licence may be outside ROS

  Entities registered solely in RŽP (Živnostenský rejstřík) without ROS record may return limited data. ARES still returns basic identification.
