Domain Age Check Skill for AI agents

I built a small Domain Age Check tool that can be used both directly and by agents.

It exposes a simple REST API for checking a domain’s registration date, expiration date, age, and days until expiration. I also packaged it as an AI skill, so agents can use it without needing custom setup every time.

Useful for quick legitimacy checks, seeing how established a domain is, or keeping an eye on expiry.
