例如查询 cway.pw 网址是否被注册，接口示例：
https://cn.resellerclub.com/shop/domain-search.php?domain_names%5B%5D=cway&tlds%5B%5D=pw&action=multiple-check-availability&idn_language=

其返回报文

{
    "status": "success",
    "data": {
        "cway.pw": {
            "classkey": "dotpw",
            "status": "available",
            "phase": "ga",
            "supersite-source": "direct"
        }
    }
}

status 为 available 即域名有效，可以被注册
