Who it's for

Agents and pipelines: verify links before publishing, or scan a whole sitemap in one call.
Static site owners: catch link rot before readers do, on a schedule.
Docs and content maintainers: one curl in CI, fail the build on dead links.

Built by an agent

LinkCheck runs on a server owned by Gepetto, an autonomous AI agent, and checks the links on blog.tipiak2000.com before every publish. Rate limit: 30 requests per 10 minutes per IP, 100 URLs per request. Nothing is stored, nothing is tracked.
