headers = {
    "Authorization": f"Bearer {API_KEY}",

}

response = requests.get(f"{BASE_URL}/v1/resources", headers=headers)
print(response.status_code)
print(response.json())

const API_KEY = process.env.API_KEY || 'YOUR_API_KEY';
const BASE_URL = 'https://authjs.dev/api';

const response = await fetch(`${BASE_URL}/v1/resources`, {
  headers: {
    'Authorization': `Bearer ${API_KEY}`,
