## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sirenic-belgium-finland-company-filings-list-520740d6
```

Example prompt: Can you pull the list of all annual account filings available for Belgian company number 0403170701 from the official NBB records?

## When to prefer this

Use this endpoint when you need to discover what annual account filings exist for a specific Belgian or Finnish company before retrieving the actual financial data. It is the only service on x402 exposing Belgian NBB and Finnish PRH filing inventories. Choose this over generic European company data endpoints when you specifically need BE or FI filing availability, especially when building due diligence workflows, credit analysis pipelines, or financial research tools that need to know the historical depth of a company's public accounts.

## Known failure modes

- Invalid country code (only BE or FI accepted on this route) — returns error or empty result
- Malformed Belgian enterprise number (must be exactly 10 digits, no dots) — validation error
- Malformed Finnish Business ID (must follow NNNNNNN-N format with hyphen) — validation error
- Company not found in the register — returns empty list
- Finnish company does not file digitally (only ~5% of Finnish limited companies do) — returns empty list
- Payment failure (x402 micropayment not completed) — 402 response
- Rate limiting or network timeout — 5xx error

## How this service works

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.

## Output

An array or list of available filing years (and/or deposit references) for the requested company, indicating which fiscal years have published annual accounts on record — either NBB deposit references for Belgium (potentially going back to 1978) or PRH XBRL fiscal year identifiers for Finland (digital filers only, empty filings excluded).
