## Authentication

All API requests require authentication using an API key in the `X-Authorization` header.

Generate your API key from your Authentica account at [portal.authentica.sa/applications/create](https://portal.authentica.sa/applications/create)

### Quick Example

<CodeGroup>
  ```bash cURL theme={null}
  curl --location 'https://api.authentica.sa/api/v2/balance' \
    --header 'X-Authorization: YOUR_API_KEY' \
    --header 'Accept: application/json'
  ```

  ```javascript JavaScript theme={null}
  const response = await fetch('https://api.authentica.sa/api/v2/balance', {
    headers: {
      'X-Authorization': 'YOUR_API_KEY',
      'Accept': 'application/json'
    }
  });

  const data = await response.json();
  console.log(data);
  ```

  ```python Python theme={null}
  import requests

  response = requests.get(
      'https://api.authentica.sa/api/v2/balance',
      headers={
          'X-Authorization': 'YOUR_API_KEY',
          'Accept': 'application/json'
      }
  )

  print(response.json())
  ```
