Look up or search the global LEI (Legal Entity Identifier) registry — the authoritative ISO 17442 directory of ~2.6M legal entities worldwide. Pass `lei` for an exact 20-character LEI, or `query` to search by legal/other name (ranked best-match first). Filter name search by `country` (ISO 2-letter, HQ country) and `status` (active = currently active entities only; all = default). Each result returns the LEI, legal name, an alternate/other name, legal jurisdiction, entity category (GENERAL/FUND/BRANCH/…), ISO 20275 legal-form code, entity status (ACTIVE/INACTIVE), LEI registration status (ISSUED/LAPSED/RETIRED/…), headquarters city/region/country/postal code, the initial registration + last update + next renewal dates, and the managing LOU. Use this to canonicalize a company name to its LEI, resolve a counterparty, or enrich a vendor master. Data: GLEIF Golden Copy (CC0, public domain).
