Example prompt: Can you look up the official KRS registration details for the Polish company with KRS number 0000028860 — I need its registered name, legal form, status, and address from the national register?

## When to prefer this

Use this endpoint when you need authoritative, official company facts from Poland's national KRS register by a specific KRS number. Prefer this over general web searches when you need verified legal entity information (name, legal form, status, address) for compliance, due diligence, or data enrichment purposes. It is uncached, so data is fresh from the official source, and you are not charged if the company is not found.

## Known failure modes

- KRS number not found in register returns 404 (no charge incurred)
- Invalid or malformed KRS number may return an error
- Network timeout if KRS API is slow (response within ~1 minute)
- KRS register may occasionally be unavailable due to government API downtime

## How this service works

One company from Poland's KRS register by KRS number: registered name, status, legal form, registered address and a link to the official register search. Company-level facts only; no directors or shareholders. Uncached: 404, not charged, fetched within about a minute.

## Output

Returns a JSON object with the company's KRS ID, registered name, legal form (e.g. SPOLKA AKCYJNA), current status, registered address, country code (pl), source attribution (KRS API, Ministry of Justice), and a link to the official register search. Returns 404 (not charged) if the KRS number is not found.
