Summary of the AI readings · beta

The service lists 11 capabilities, and 10 have AI readings.

10 capabilities are read as read-only, including find_alternatives, search_apps and list_categories.

Rows named: find_alternatives · search_apps · list_categories

Written by code from the AI readings on this page: it groups them and says nothing they do not.

The atlas shows each capability by its plain identifier, inputs and declared sign-in. Publisher descriptions, paths, links and source evidence are not published here.

The entry is one exact observed target, not a real-world service identity, and implies no ownership. Endpoint paths are not published; the locator hash lets an operator confirm their own URL.
