如何在google play开发者API中检测google play订阅费用？

import requests

def check_subscription_cost(api_key, package_name, subscription_id):
    url = f"https://play.googleapis.com/admin/subscriptions/{package_name}/purchases/{subscription_id}/tokens/your_token"
    headers = {
        "Authorization": f"Bearer {api_key}"
    }
    response = requests.get(url, headers=headers)
    
    if response.status_code == 200:
        subscription_info = response.json()
        cost_micros = subscription_info["subscriptionPurchase"]["priceAmountMicros"]
        currency_code = subscription_info["subscriptionPurchase"]["priceCurrencyCode"]
        cost = float(cost_micros) / 1000000
        print(f"The cost of the subscription is {cost} {currency_code}.")
    else:
        print("Failed to retrieve subscription information.")

# 使用你的API密钥、应用程序包名和订阅ID调用函数
check_subscription_cost("YOUR_API_KEY", "com.example.app", "subscription_id")
