Japanese-market code review agent. Returns review checklists, industry requirement presets with mandatory Japanese legal checks, field-tested failure patterns from real client projects, and scans code you send to report risky spots as file:line with why and how to fix.

    Give an AI agent a stable, routable IPv6 address of its own and egress that anyone can verify from outside. Use this when you need a fixed IP your traffic actually leaves from, an identity another service can check independently by reverse DNS and RDAP rather than taking your word for it, or control over what an agent is allowed to reach and a record of what it did. It also answers security questions about any domain, address or file hash from the Whisper graph, with no account at all. The address space is AS219419, which we run; an email address alone is enough to get a key.
