# API Endpoints Guarded by API Keys

A complete reference of all Fusionauth REST API Endpoints that leverage API Keys with their supported HTTP methods.

> For the index of this section of the site, see [llms.txt](https://fusionauth.io/docs/llms.txt)

FusionAuth exposes a REST API. This page lists API endpoints that leverage API Keys along with the supported HTTP methods.

For full request and response documentation, see the [API reference](https://fusionauth.io/docs/apis.md).

## Authentication

The **Auth** column shows the API key scope required for each endpoint:

*   ![API Key Authentication](https://fusionauth.io/img/icons/api/api-key-authentication.svg) [API Key Authentication](https://fusionauth.io/docs/apis/authentication.md#api-key-authentication) — a tenant-scoped or global API key may be used.
*   ![Global API Key Authentication](https://fusionauth.io/img/icons/api/global-api-key-authentication.svg) [Global API Key Authentication](https://fusionauth.io/docs/apis/authentication.md#global-api-key-authentication) — only a global API key may be used.
