GLEIF Automates Access to the LEI Data Pool with LEI Look-up API

Subscribe to our newsletter

The Global Legal Entity Identifier Foundation (GLEIF) has responded to financial industry requests to be able to include LEI data in automated processes by providing an application programming interface (API). The API is called LEI Look-up and is designed to provide automated access to the Global LEI Index of current and historical LEI records.

The GLEIF has taken action on automation after a beta test carried out earlier this year with LEI stakeholders, including financial institutions, regulators and analysts, showed the need to automate the integration of LEIs with in-house systems.

LEI Look-up allows developers to access directly the LEI data pool in real time and perform on-demand checks for changes to specific LEI records in an easy-to-read format. It is possible to find up to 200 LEI records included in the Global LEI Index with one request to the API, allowing users to retrieve information on specific LEIs without having to download GLEIF Concatenated Files or search manually for individual records using the LEI search tool.

The GLEIF expects the integration of LEI look-up functionality with in-house systems to support processes requiring LEIs such as Know Your Customer (KYC), client onboarding and regulatory reporting. The API can be integrated using the JSON data format and is free of charge and registration requirements.

Don’t miss the opportunity to respond to the LEI Regulatory Oversight Committee’s consultation on Corporate Actions and Data History in the Global LEI System. It closes this Friday, September 29, 2017. You can find out more about the consultation here.
