## Authentication
API keys are required for all API and MCP requests and are tied to your Lusha account and plan. To access the Lusha API, you must authenticate your requests using your API
key. This key is unique to your account and is used to identify your usage
of the API.
**How to Authenticate:**
When making an API call, include your API key in the `api_key` header of the request.
> You can generate and retrieve your API key [here](https://dashboard.lusha.com/enrich/api).

API keys should be stored securely and used only in server-side environments.
