LEI Registration API

Build LEI registration & renewal directly into onboarding, KYC/KYB or applications.

You’ve got an idea in mind of how LEIs can add value to your product, your workflow or your bottom line. Let’s get it to production. The LEI Registration API guides and reference docs will get you across the deploy line using the language of your choice.

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 & organisations, 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 applications and workflows. The RapidLEI automation logic will handle the complexity of the application validation.
