[MNT] Replace Live Server Calls with Mocks in Unit Tests about 1 hour ago

AI Summary: This issue addresses the problem of unit tests directly connecting to a live server, which causes instability, race conditions, and sporadic failures. The goal is to refactor these tests to use mocks or patches, specifically targeting `requests.Session` or higher-level API calls, to ensure they function as true unit tests. This will improve test reliability and prevent server overload.

Complexity: 3/5
