```

Example prompt: Can you look up the Slovak company with ICO 31333532 in the official Slovak business registry and tell me its current name, legal form, registered address, and whether it's still active?

## When to prefer this

Use this endpoint when you need authoritative, official company data for Slovak legal entities specifically, sourced directly from the Statistical Office of the Slovak Republic's RPO register. Prefer this over general web searches or third-party business databases when you need legally accurate ICO, legal form, address, or establishment/termination data for Slovak entities. It also handles historic company name lookups, making it useful for tracing rebrands or restructurings.

## Known failure modes

- No results found if the ICO or name does not exist in RPO
- ICO must be exactly 8 digits; malformed queries may return empty results
- Name query requires at least 3 characters
- limit parameter must be between 1 and 5; out-of-range values may error
- Personal data of sole traders is stripped; results for individuals will be incomplete
- Stale data possible within the 24-hour cache window
- Service unavailability or timeout from upstream api.statistics.sk

## How this service works

Official Slovak business registry (RPO) search via api.statistics.sk (Statistical Office of the SR). Query: ?q=31333532 (8-digit ICO) or ?q=eset (name; historic names also match, current-name hits rank first). Optional active_only=true, limit 1-5. Returns per entity: ICO, current name, legal form, address, source register, establishment/termination dates. Personal data of individual entrepreneurs is stripped (GDPR). 24h cache.

## Output

Returns a list of matching Slovak legal entities (up to the requested limit), each containing: ICO (8-digit identifier), current company name, legal form, registered address, source register, establishment date, and termination date if applicable. Personal data of individual entrepreneurs is omitted per GDPR. Results are cached for 24 hours. Current-name matches are ranked above historic-name matches.
