In 2019, GLEIF provided access to the beta version of its new GLEIF API to a selected number of users. After we have received and incorporated valuable feedback from our user groups to date, GLEIF has made the API now available as a public beta earlier in 2020 and has released the production service in fall of 2020. The GLEIF API gives developers access to the full LEI Data search engine functionality, including filters, full-text and single-field searches of legal entity and ownership data, and “fuzzy” matching of relevant data fields such as names and addresses. In addition to LEI reference data, the GLEIF API also makes available further related data, e. g. reference data of LEI issuers, code lists used in LEI records and mapped identifiers like BIC or ISIN codes.

For example, using the GLEIF API, you can search for LEIs via entity names, find LEIs by BIC code or investigate corporate structures (search for parent and child relationships). The GLEIF API is based on the data found in the GLEIF Golden Copy.

Full documentation on the GLEIF API, as well as a demo application, are available with the below links.
