ARES (Administrativní registr ekonomických subjektů, Administrative Register of Economic Entities) is the Czech Ministry of Finance's information system that aggregates public data on economic entities from source registers -- the Commercial Register (VR), Trade Licensing Register (RŽP), Statistical Business Register (RES), health-provider, church, foundation and other registers. It publishes a free, anonymous public REST API (OpenAPI 3.0, v1.4) for looking up and searching entities by IČO, address standardisation, code lists and change-notification batches.
