LEI Registration API

Build Legal Entity Identifier registration & renewal directly into onboarding, KYC/KYB or applications using Verified Organizations.

LEI Registration API - RapidLEI

The RapidLEI LEI Registration API gives developers the flexibility to build automated LEI issuance and management into applications quickly and easily.

The LEI Registration API makes searching for LEIs & organizations, and then registering and issuing Legal Entity Identifiers easy and fast. Use the executable API descriptions (Postman Collection), documentation, sample code, and developer tools you need to easily build same-session LEI issuance into Know Your Customer (KYC) / Know Your Business (KYB) applications and workflows. The RapidLEI automation logic will handle the complexity of the application validation.
