Other data sources
Company data in every jurisdiction is also spread across sources outside the commercial register — the central bank, the official gazette, the financial supervisor's authorisation registers, the statistical office and the tax authority among them. Kausate draws only on the sources described on this page; when you need something the API does not carry, those are where to look.
