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 in the path 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. A search parameter, by contrast, is cleaned up: unsupported characters are stripped and the usable query is served.

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.

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.

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 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 and in llms.txt.
