Api Endpoint

Sirenic

Czech company insolvency from ISIR, the official insolvency register of Czechia, since 2008. Query: /v1/eu/entreprise/CZ/45274649/insolvabilite (8-digit IČO). Every proceeding, bankruptcy (konkurs) or reorganisation (reorganizace): case number, court, status, dates, its 100 most recent events with document links. Publication is compulsory by law: no proceeding is an explicit positive answer. LEGAL PERSONS ONLY: a natural person's IČO (sole trader, like most Czech IČOs) is refused, never cleared.
