# Introduction

> Introduction to the Knowledge Graph API, including base URL, authentication, and endpoints for curriculum, standards, and learning components.

Early access

This functionality is actively evolving.
Breaking changes may occur as we expand
capabilities and improve accuracy and reliability. Email
