## 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 sirenic-polish-krs-company-events-e6ed95f6
```

Example prompt: Pull the full official KRS event history for Polish company 0000006865 — I need to see any liquidation, bankruptcy, restructuring, mergers, name changes, or other corporate events recorded in the Ministry of Justice bulletin.

## When to prefer this

Use this endpoint when you need a structured, typed, GDPR-compliant event timeline for a specific Polish company identified by its 10-digit KRS number — especially for due diligence, compliance auditing, supplier vetting, or investment screening. Prefer it over general company data endpoints when the specific need is corporate lifecycle events (liquidation, bankruptcy, mergers, restructuring) rather than static firmographic data. It is purpose-built for Polish KRS data from the official Ministry of Justice daily bulletin, making it more authoritative and structured than web scraping or secondary data providers.

## Known failure modes

- Invalid or malformed KRS number (not 10 digits or wrong format) returns an error
- KRS number not found in the registry returns empty or 404
- No events recorded for a valid company returns an empty event list
- KRS number provided is a NIP or REGON instead of KRS, causing a lookup failure
- Rate limiting or payment failure (x402) if USDC payment not completed

## How this service works

Polish company registry EVENTS from the official KRS daily bulletin (Ministry of Justice) — company monitoring for Poland. Query: /v1/eu/entreprise/PL/0000006865/evenements (KRS number). Liquidation, bankruptcy, restructuring, mergers, suspension/resumption, dissolution, tax arrears, enforcement, accounts filings, name/seat/capital changes, strike-off — each typed from a CLOSED list, dated, traced to its section, in a gap-free window. GDPR by design: no officer, no PESEL, no register free text.

## Output

A structured, chronological list of typed corporate events for the specified Polish company, each entry including the event type (from a closed controlled vocabulary such as liquidation, bankruptcy, restructuring, merger, dissolution, name change, capital change, accounts filing, tax arrears, enforcement, suspension, strike-off), the event date, and the reference to the register section it appeared in. No personal data (no officer names, PESELs, or free register text) is included by design.
