Belgian and Finnish annual accounts

A rare archive depth: Belgian filings go back to 1978. On the Finnish side the limit is stark and worth stating — only about 5% of Finnish limited companies file digitally. Empty filings are filtered out, so every listed year genuinely carries figures. 60,889 rows of Finnish accounts are in the database.

What the route returns

Catalogue description, exactly as agents read it:

European company financials — Belgian and Finnish company annual accounts, filings list. BE: every published deposit reference at the NBB CBSO (Central Balance Sheet Office, Authentic Data, since 1978), 10-digit enterprise number. FI: fiscal years available as PRH XBRL filings (~5% of Finnish limited companies file digitally; empty filings are filtered out, every listed year carries figures), Business ID NNNNNNN-N. Unique on x402: no other service exposes Belgian or Finnish filed accounts.

Expected identifier

Belgium: 10-digit enterprise number. Finland: identifier in the NNNNNNN-N format, hyphen included.

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.

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.
