About this API
JAR (Juridinių asmenų registras) is Lithuania's register of legal entities, maintained by Registrų centras. The data is served by the national open-data portal data.gov.lt on the Spinta engine, which lets you search and filter entities by code (ja_kodas), name, legal form or registration date, with pagination. Returned fields include name, address, registration and deregistration dates, legal form and status. No key required.
