AI agent discovery checker
Agents do not guess URLs: they follow Link headers, catalogs and indexes. One domain, five checks for every machine-discoverable entry point your site offers.
Included in the free full scan — run this category alone when you only need these checks.
Checks site-wide files at the domain root — any page URL on the domain gives the same result.

Frequently asked questions
How do AI agents discover my site?
Through machine-readable pointers: Link headers on the homepage, an API catalog linkset, a skills index, a DNS organization record — then Markdown negotiation to read pages cheaply.
What is Markdown negotiation?
The server returns text/markdown when the client sends Accept: text/markdown. Agents fetch fewer tokens and cite more cleanly; the response must carry Vary: Accept.
What each check verifies, and what a failure looks like, lives in the checker library.
