# Authentication

> Learn how to authenticate your API requests.

Prism API uses API keys to authenticate requests. Every API request must include your API key in the `x-api-key` header to verify your identity and permissions.

<Warning>Your API key is sensitive information that grants access to your Prism account. Never expose it in client-side code, public repositories, or browser-accessible areas.</Warning>
