Legal Entity Identifier (ISO 17442)
The Legal Entity Identifier is a 20-character code identifying a legally distinct entity participating in financial transactions, standardised as ISO 17442 and operated by GLEIF through accredited issuers. It exists because the 2008 crisis revealed that no one could reliably say which entity was counterparty to which exposure.
Also known as Legal Entity Identifier, ISO 17442, GLEIF LEI, vLEI.
Providers that carry LEI 1
These providers' own APIs.json profiles carry LEI as a tag — the provider's statement that the standard is part of what it does. APIs.io has not verified the implementation on this page; the de facto profiles on this site are where that measurement exists. Ordered by Kin Score.
