# Getting started

In order to authenticate your requests to the Radiant API, we use API Keys. It is important to keep your API Key private and secure.

## Create API Key

Request your API key [here](https://92oi0iel400.typeform.com/to/CgF917Vg).

## Basic Example

All API calls require the `x-api-key` header and contain your API Key. For an example of how to do this, see the code snippet below:

```bash theme={null}
curl 'https://api.segment.radiant.so/v1/segment/f67ec811-1a01-4ad5-83fe-0d743912b138' \
  -H 'content-type: application/json' \
  -H 'x-api-key: your-key'
```
