引言
域名Whois信息查询V2是增强版域名注册信息查询接口。相较于V1版本，它在数据字段完整性和查询稳定性上进行了优化，支持通过标准HTTP Header进行鉴权，旨在为开发者提供结构化的域名生命周期管理数据，适用于批量监控与资产盘点场景
1.注册起零数据平台 2.登录控制台，右上角--获取API的TOKEN密钥即可

动态签名算法开通方式情参考《开发文档》
Header封装【推荐】
参数拼接【安全性低】

企业IT或域名投资机构可利用此API构建自动化监控系统。通过定时轮询（Cron Job）调用接口，批量检查名下域名的expirationDate（过期时间）和states（状态），一旦发现临近过期（如30天内）或状态异常（如clientHold），立即通过邮件或钉钉机器人触发告警，避免因域名过期导致的业务停摆。
expirationDate
states
在SOC（安全运营中心）或欺诈检测系统中，集成该接口用于快速甄别恶意域名。通过查询陌生域名的creationDate（创建时间）和registrar（注册商），结合“新注册域名”与“短生命周期”等特征，辅助判断钓鱼网站或僵尸网络域名的风险等级，为黑名单库提供数据支撑。
creationDate
registrar
建站平台或商标监测服务可在用户注册环节调用此API。例如，用户输入心仪域名后，前端实时展示该域名的注册状态（是否可注册）及历史信息；或在商标保护场景中，通过owner字段模糊匹配，监测是否存在与客户品牌相似的侵权域名。
owner
域名Whois信息查询V2 API将分散在各注册商的非结构化Whois文本转化为标准JSON，极大降低了数据处理成本。对于需要高频、批量获取域名“身份信息”的业务，它是构建自动化运维与安全风控体系的底层数据引擎。特别提示：尽管接口支持URL参数拼接，但文档明确建议使用Header传参（Authorization: Bearer <token>）以保障密钥安全。
