Summary of the AI readings · beta

The service lists 5 capabilities, and 5 have AI readings.

5 capabilities are read as read-only, including search_companies, get_parcel_profile and get_company.

Rows named: search_companies · get_parcel_profile · get_company

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.
