# 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.

## 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/{pays}/{id}/comptes

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

# 3. Ou en MCP, dans Claude Code / Cursor / un agent

## Neighbouring routes

- `/v1/eu/entreprise/{pays}/{id}/comptes/{reference}` — $0.15
- `/v1/eu/entreprise/BE/{id}` — $0.01
- `/v1/eu/entreprise/FI/{id}` — $0.01

## 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**
