Example use cases
Supplier due diligence check
“I need to verify a Polish supplier before signing a contract — can you look up KRS number 0000033014 and tell me their legal form, whether they're active, their registered address, and current board members?”
Batch KRS lookup for investor screening
“I have a list of Polish companies I'm evaluating: KRS numbers 0000019193, 0000033014, and 0000123456. Can you pull their names, legal status, NIP, REGON, share capital, and board members from the KRS register for all three at once?”
Foundation and NGO registry check
“Can you look up KRS number 0000654321 in the associations and foundations registry (S) and get me the full details — name, status, address, and registration date?”
Technical details
Endpoint
POSThttps://x402-agent-tools.nerolabs.workers.dev/company/poland?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, structured data about Polish legal entities directly from the official KRS court register — particularly for due diligence, compliance checks, supplier verification, or enriching business records with NIP, REGON, board composition, and share capital. Prefer this over web scraping or unstructured sources when verifiable legal accuracy matters. For Irish companies use the sibling CRO endpoint; for UK companies use the Companies House sibling endpoint.
Side effects
- Invalid or non-existent KRS number returns no record or error
- Wrong registry type (P vs S) causes no match for valid KRS number
- KRS number not zero-padded to 10 digits may fail lookup
- Batch exceeds 20 KRS numbers — only first 20 may be processed
- KRS register temporarily unavailable causing upstream errors
- Partial name masking on board member fields (privacy redaction by source)
