Summary of the AI readings · beta

The service lists 13 capabilities, and 13 have AI readings.

12 capabilities are read as read-only, including get_calculator_stats, get_tax_treaty_text and get_revenue_ebrief_changelog.

Rows named: get_calculator_stats · get_tax_treaty_text · get_revenue_ebrief_changelog

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.
