Profile of a Polish company

A deliberate design decision for this country: we do not serve the free text of the Polish register, because it names natural persons. What is served is structured and minimised. It is less rich than the source, and that is on purpose.

What the route returns

Catalogue description, exactly as agents read it:

Official Polish company registry lookup (KRS — Krajowy Rejestr Sądowy, the National Court Register of Poland, Ministry of Justice). Query: /v1/eu/entreprise/PL/0000006865 (10-digit KRS number). Returns legal name, legal form, normalized status, incorporation date and registered office — Polish company data live from KRS (officers anonymized at the source). Unified JSON schema shared by all Sirenic European company profiles.

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.

Price and billing

Price: $0.01. 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
curl -i https://api.sirenic.eu/v1/eu/entreprise/PL/{id}

# 2. L'appel réglé — le client x402 paie le devis et rejoue la requête
npx x402-fetch https://api.sirenic.eu/v1/eu/entreprise/PL/{id}

# 3. Ou en MCP, dans Claude Code / Cursor / un agent
claude mcp add --transport http sirenic https://api.sirenic.eu/mcp

What this route does not do

Live query at the register: always current, but dependent on its availability. A register outage returns 503 and the call is not billed — never a degraded response.

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.
