Danish company registry filings from the official virk.dk publication index (Erhvervsstyrelsen), Denmark: the fiscal years whose XBRL annual report has been decoded, 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. A sole proprietorship or undecided CVR form: 404, not billed. Unique on x402: no other service exposes decoded Danish filed accounts.
