+)
+
+func main() {
+
+	// Load .env file
+	err := godotenv.Load(".env")
+	if err != nil {
+		log.Fatalf("Error loading .env file")
+	}
+
+	xApiKey := os.Getenv("X_API_KEY")
+
+	// Load in Service Account Json - Currently only supports from file
+	sa, err := service_account.FromFile("./api-service-account-key.json")
+	if err != nil {
+		log.Fatalf("Failed to load service account: %v", err)
+	}
+
+	// Create ComboCurveAuth
+	auth, err := combocurve_auth.NewComboCurveAuth(&sa, xApiKey, 60, 60*60)
+	if err != nil {
+		log.Fatalf("Failed to create ComboCurveAuth: %v", err)
+	}
+
+	// Get auth headers
+	headers, err := auth.GetAuthHeaders()
+	if err != nil {
+		log.Fatalf("Failed to get auth headers: %v", err)
+	}
+	fmt.Printf("Auth headers: %v\n", headers)
+
+	// Make request
+	url := "https://api.combocurve.com/v1/monthly-productions?take=1"
+	method := "GET"
+
+	client := &http.Client{}
+	req, err := http.NewRequest(method, url, nil)
+
+	if err != nil {

+		return
+	}
+	req.Header.Add("x-api-key", headers["x-api-key"])

+
+	res, err := client.Do(req)
+	if err != nil {
+		fmt.Println(err)
+		return
+	}
+	defer res.Body.Close()
+
+	// Print response
+	body, err := io.ReadAll(res.Body)
+	if err != nil {
+		fmt.Println(err)
+		return
+	}
+	fmt.Println(string(body))
+
+	// Get next page url - similar to python library, this will just be an empty string is nothing further availble to proceed
+	nextLink := pagination.GetNextPageURL(res.Header)
+
+	fmt.Println(nextLink)
+}
