GLEIF LEI Look-up API - How To

The Global Legal Entity Identifier Foundation (GLEIF) Legal Entity Identifier (LEI) Look-up API provides developers with the opportunity to directly access the complete LEI data pool in real time and to perform on-demand checks for changes to specific LEI records in a convenient, easy-to-read format.

The API responds to market needs as identified during a beta test, carried out in 2017, which involved multiple LEI stakeholders including financial institutions, regulators, fintech companies and analysts seeking to include LEI data in automated processes.

GLEIF provides services that empower market participants to take advantage of the wealth of information available within the LEI data pool.

The GLEIF LEI Look-up API further contributes to meeting this goal by enabling any interested party to quickly obtain updates with regard to a pre-defined list of up to 200 LEI records.

Some examples of usage are:
  • Know-your-customer (KYC)
  • Client onboarding
  • Compliance
Use of the API is free of charge and does not require registration. GLEIF does not enter into individual contractual relationships or administrative processes with specific users of the LEI data.

The LEI Data Terms of Use, covering access, service levels, and legal terms, apply to the API.
