# PyKS2: reconstructing the Pentax K-S2 Wi-Fi API

> PyKS2 reconstructs the Pentax K-S2 camera's undocumented Wi-Fi HTTP and WebSocket interface as a Python library, CLI and camera simulator. Its protocol notes map endpoint groups, request behavior, live view and event streams, backed by captured responses from firmware 01.10.
