## 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-danish-xbrl-filing-history-8cd983a8
```

Example prompt: Can you pull up the list of decoded XBRL annual report filings for Danish company CVR 41235292 — I want to see which fiscal years are available, their closing dates, and what currency they report in?

## When to prefer this

Use this endpoint when you specifically need the list of available decoded Danish annual report filings for a company identified by its 8-digit CVR number. It is uniquely suited for Danish FSA-taxonomy filers on the virk.dk register. Do not use if the company files under IFRS/ESEF only, or if you need the actual financial statement data (this returns the index/list, not the full accounts). No other x402 service exposes decoded Danish filed accounts.

## Known failure modes

- Invalid or non-existent CVR number returns an error or empty result
- CVR belongs to a company that files only under IFRS/ESEF taxonomy — not decoded, returns empty or note
- CVR number not exactly 8 digits — schema validation error
- Company has never filed XBRL accounts — empty list returned
- API payment failure (x402 payment required not fulfilled)

## How this service works

Danish company registry filings from the official virk.dk publication index (Erhvervsstyrelsen), Denmark: the fiscal years whose XBRL annual report has been decoded — the entry point to Danish annual accounts and financial statements — with closing dates, period, entity name and currency. 8-digit CVR number. Danish-taxonomy (fsa) filings only: IFRS/ESEF-only groups are not decoded, absence does not mean no accounts exist. Unique on x402: no other service exposes decoded Danish filed accounts.

## Output

A list of decoded XBRL annual report filings for the specified Danish CVR, each entry containing the fiscal year closing date, reporting period (start and end), entity name as filed, and reporting currency. Covers Danish-taxonomy (FSA) filings only; IFRS/ESEF-only companies are not included.
