# API Reference Overview

> Choose the API reference for the Utexo service you are integrating.

Utexo does not expose one global API contract. The Mint service, RGB Node, RGB Lightning Node and Utexo Cloud have separate endpoints, authentication models and release lifecycles.

<Info>
  Each product has its own API contract. Use the reference for the specific service you are integrating.
