Belgian and Finnish annual accounts

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 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: $0.01. 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.
