# Api Documentation

### Authentication

To use the Noiz API, users must first register an account with their email address.

After registration, the developer will provide the user with a unique **API Key** associated with their account. This API Key must be included in the `Authorization` header of every request.

Example header:

```http
Authorization: <YOUR_API_KEY>
```

Keep your API Key secure. Do not share it publicly or embed it in client-side code.
