# Overview

> Use the Openlayer REST API to interact with Openlayer

You can directly access a subset of our backend endpoints through **HTTPS**.

## Base URL

The Openlayer API is built around **REST**. All requests are made to endpoints
that begin with:

```text theme={null}
https://api.openlayer.com/v1
```

## Authentication

The Openlayer API uses **API keys** to authenticate requests. You refer to the [Create an
API key guide](/workspace-and-projects/find-your-api-key) for details on how to locate your key.

To authenticate an API request, you should provide your API key in the `Authorization` header.

```text theme={null}
Authorization: Bearer YOUR_API_KEY_HERE
```
