# Polish register events

This route's freshness is not measured like the others, and that is instructive: the clock is not our ingestion date but the end of the observation window. A job can succeed every night while the window ages — tracking the ingestion date would show “current” on a route that is closing.

## What the route returns

Catalogue description, exactly as agents read it:

**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.**

## Expected identifier

Polish KRS number.

> ⚠️ A wrongly formatted identifier returns `400` and is **not billed** — but it costs you a round trip. It is the leading cause of failed calls on the foreign routes.

## Extract from a genuinely paid response

Dated snapshot from 2026-07-29, truncated to one item per array. It is not live data. The full extract is served **free of charge** from [the samples surface](https://api.sirenic.eu/exemples/), and the schema from the OpenAPI document.

Pour trancher l'existence, appeler la fiche d'identité LIVE (elle rend 404 si le KRS n'existe pas). / Existence NOT verified: this route only reads the daily bulletin and this number never appeared in it during the window; an unknown number yields the very same answer.

## Price and billing

Price: **$0.02**. The authoritative amount is the one in the `402` quote returned by the route itself — not this text, which derives from the same grid but is still just a page.

An error response **cancels the payment**: a `400`, `404` or `503` is never billed. An upstream outage closes the route with a `503` rather than serving a degraded response.

## Calling the route

```
# 1. Le devis, sans rien payer : la route répond 402 avec son montant

# 2. L'appel réglé — le client x402 paie le devis et rejoue la requête

## What this route does not do

The Polish register's **free text** is not served: it names natural persons. What is returned is structured and minimised.

## Neighbouring routes

- `/v1/eu/entreprise/PL/{id}` — $0.01
- `/v1/eu/facturation/dossier` — $0.03

## How you pay

Every route is paid **per call**, in USDC or EURC on the Base network, over the x402 protocol: no account to create, no API key, no subscription. The first call returns a `402` quote your client settles, then replays the call. A failed call is never billed.

Would you rather have a euro invoice and prepaid credits? That is **in preparation**, and we will not announce a date until it is open. Write to [contact@sirenic.eu](mailto:contact@sirenic.eu?subject=Euro%20credit%20packs) and we will let you know when it opens.

Paid responses are **Ed25519-signed**: you can later prove what was served to you, and when. The whole catalogue is free to read in the [OpenAPI document](https://api.sirenic.eu/openapi.json) and in [llms.txt](https://api.sirenic.eu/llms.txt).

**One call, end to end**
