Summary of the AI readings · beta

The service lists 2 capabilities, and 1 has AI readings.

get_credits is read as read-only.

Rows named: get_credits

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.

A2A skills 0+ observed

Inventory incomplete. The displayed count is a lower bound; missing items do not prove removal.

None recorded in this Passport.

Declared and observed

2 tools declare hints; the AI readings agree with all 1 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: 3 Nov 2026, 21:26 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.
