import requests

def safe_api_call(api_key, endpoint, data):
    # 1. 先查额度
    balance_url = "https://api.dmxapi.com/v1/balance"
    balance_res = requests.get(balance_url, headers={"Authorization": f"Bearer {api_key}"})
    if balance_res.status_code != 200 or balance_res.json()["remaining_balance"] <= 0:
        raise Exception("额度不足，请充值后重试")
    
    # 2. 正常调用API
    api_url = f"https://api.dmxapi.com/v1/{endpoint}"
    res = requests.post(api_url, json=data, headers={"Authorization": f"Bearer {api_key}"})
    return res.json()

# 使用示例
try:
    result = safe_api_call("your-api-key", "your-endpoint", {"param": "value"})
    print(result)
except Exception as e:
    print(f"错误：{e}")
