AI 分析

痛点：IP/域名被封锁时，无法快速知道是哪些黑名单标记以及如何申请移除，单一风险评分不够用。

目标用户：运维、邮件送达率工程师、安全分析师、SaaS 开发者、需要排查 IP/域名信誉的团队。

证据：A single risk score doesn't help when you need to know who to ask for delisting. You're only charged for answers. A failed or rate-limited lookup costs nothing.

变现：按查询次数付费的 API（credits），免费层 100 credits/月，对高用量用户提供订阅套餐和企业定制。

MVP：2 周 MVP：聚合 5-10 个主流 DNSBL/公开黑名单，提供 REST API 查询 IP/域名，返回每个名单的命中状态、原始来源链接、首次/末次出现时间；用 Stripe 按 credit 计费，免费 100 次/月。

竞品：AbuseIPDB、VirusTotal、IPQualityScore、MXToolbox Blacklist Check、HetrixTools Blacklist Monitor、Spamhaus、Scamalytics

摘要：作者发布 Senapati，一个 IP/域名/URL/邮箱信誉 API，聚合多个公开黑名单、DNSBL 和威胁情报引擎，返回每个引擎的判定及来源链接，并按成功查询收费。它解决被封锁后不知该向谁申请移除的痛点，但已有 AbuseIPDB、VirusTotal、MXToolbox 等成熟竞品，且帖子未展示真实付费用户或收入。
