More from Eckari & similar services
Eckari · UK Directors
api-staging.eckari.com
Return the officers registered against a UK company on the Companies House register — directors, secretaries, LLP members and corporate officers — with role, appointment and resignation dates, nationality, country of residence, occupation, month/year of birth and public correspondence address. Active officers by default; include_resigned adds history. Paging is explicit: has_more and next_offset say whether more matching officers remain. Use when: Who are the directors of this UK company?
Eckari · FX Reference Rate
api-staging.eckari.com
European Central Bank euro foreign exchange reference rate for a pair - the latest published fix or any date in the last 90 days. The ECB publishes EUR/XXX only, so inverse and cross rates are computed by Eckari from the same fix and named in rate_derivation. Reference rates, one per TARGET working day around 16:00 CET, not tradable market rates. Source and reuse conditions travel in meta.attribution. Use when: What is the ECB reference rate for EUR to USD?
Eckari · UK Status
api-staging.eckari.com
Return the current legal status of a UK company from the Companies House register — active, dissolved, liquidation, administration, receivership, voluntary-arrangement and others — with status detail, cessation date, a derived is_active (true for the live-on-the-register statuses active, open and registered) and a derived is_striking_off for an active company with a proposal to strike off. One call, one authoritative register answer. Use when: Is this UK company still active?
