Summary of the AI readings · beta

The service lists 13 capabilities, and 11 have AI readings.

4 capabilities are read as read-only, including get_key_dates, get_state and lookup_coordinates.

Rows named: get_key_dates · get_state · lookup_coordinates

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.

Declared and observed

13 tools declare hints; the AI readings agree with all 11 that have a reading.

A disagreement is not a finding about the service: either side can be wrong. How we compare declarations and readings.

Snapshot generated: 4 Nov 2026, 00:59 UTC

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.
