# Requesting and Using API Key

## How to request API key

API key is not required, you can use the public API without the API key. Should you require a dedicated API key, kindly open a support ticket on our [Discord](https://discord.com/invite/flytrade). In your request, please include detailed information about your project and how you intend to utilize our APIs.

## How to use API key

Include the `apikey` header alongside the request. To verify that the API key is working, check if the response contains `x-auth-status: authenticated` header.

```
$ curl -I -H 'apikey: <APIKEY>' https://api.magpiefi.xyz/ | grep -i 'x-auth-status'
```
