# Getting Started

### API Key & Authentication

Authentication is done via the API key which you can find in your [account settings](https://app.spaceserp.com/settings/api). Requests are authenticated using `apiKey` query parameter.

You can see your account’s API keys, and roll them if necessary, in the [dashboard](https://app.spaceserp.com/).
