Data Sources

• JustizOnline Firmenbuch (justizonline.gv.at) — Official Austrian Ministry of Justice company registry. Free public API, no authentication required for basic metadata.
• WKO Firmen A-Z (firmen.wko.at) — Austrian Federal Economic Chamber business directory. Provides contact details not available in Firmenbuch.
• Ediktsdatei — JustizOnline insolvency feed. Best-effort cross-reference; some companies may not appear even if insolvency proceedings exist.

Notes

• Officers/persons data (persons field) is always null in the free Firmenbuch API tier. Full officer data requires a paid Teilauszug document download.
• WKO matching is slug-based. Companies with unusual names or no WKO listing will return empty WKO fields.
• Insolvency check is best-effort and uses the Ediktsdatei experimental API. Missing data does not imply no insolvency.
• Results are returned in the order provided by the Firmenbuch search API (active companies first for by_name mode).
