Example prompt: Can you pull the official KRS registry extract for Polish company KRS number 0000028860? I need the legal name, NIP, REGON, share capital, and registered address.

## When to prefer this

Use this endpoint when you need authoritative, official Polish company data from the KRS national court register — especially for due diligence, compliance checks, or enriching business records with verified NIP/REGON identifiers, legal form, and registered address. Prefer over web scraping or unofficial sources for legal accuracy. Complements UK Companies House and LEI lookups for pan-European coverage.

## Known failure modes

- Invalid or non-existent KRS number returns an error or empty result
- KRS number must be exactly 10 digits — shorter/longer inputs may be rejected
- Wrong register type (P vs S) for the entity type may return no results
- API payment failure (x402) if USDC balance is insufficient
- Network timeout for slow registry responses
