## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability nero-labs-poland-krs-company-lookup-9cf233cd -d '<json body>'
```

Example prompt: Can you look up Polish company KRS number 0000019193 in the KRS register and tell me its legal status, NIP, REGON, address, share capital, and who's on the board?

## When to prefer this

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.

## Known failure modes

- 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)
