ISINs Linked to a Legal Entity Identifier (LEI): ISIN-LEI Mapping

gleif/get-lei-isins

One page of the ISINs (International Securities Identification Numbers) linked to a Legal Entity Identifier, from the Global LEI System's ISIN-to-LEI mapping. Give the 20-character LEI. Each record carries the LEI and one ISIN; the response reports the total number of ISINs and pages and when the Golden Copy it is based on was published. A busy issuer has hundreds of ISINs, so you choose the page size and page through them. LEI reference data from the Global LEI System (GLEIF), CC0, passed through unmodified and served by Eden Engine.
