LEI Look-up API
As part of services provided by NSD as a Local operational unit (LOU) there was implemented the "IOLITE WEB-service", which provides an interface for accessing data for all NSD-serviced LEI codes.
IOLITE WEB-service allows clients to setup their software for automatic download of real-time reference information about organizations by their LEI codes through the API (Application Programming Interface). The data transmitted through the IOLITE WEB-service includes information about LEI codes and their owners and is compliant with CDF 2.1 (Common Data File 2.1) format, approved by the Global Legal Entity Identifier Foundation (GLEIF).
The service is currently free.
The detailed procedure for connecting to the IOLITE WEB-service and obtaining information about organizations by using LEI codes through IOLITE WEB-service is described in the Guidelines, which is accessed on NSD’s official website in the section "Software".
