Screen Stocks Python Bridge

The screenstocks-bridge package is a Python client for the local API exposed by the Screen Stocks Bridge BepInEx plugin. It requires the plugin to be installed in the game and the game to be running. The package itself does not install or contact the game backend; it connects to the plugin on loopback.

Install

python -m pip install screenstocks-bridge

Install the matching BepInEx plugin from the GitHub releases, then launch Screen Stocks. The default bridge address is 127.0.0.1:48721. The plugin port can be changed under [Bridge] as Port in BepInEx/config/screenstocks.bridge.cfg; close and relaunch the game after editing it. Pass the same value to BridgeClient(port=...) when it differs from the default. The example scripts also read SCREENSTOCKS_PORT. Read the token from BepInEx/config/screenstocks.bridge.cfg or the BepInEx log.

Connect

from screenstocks_bridge import BridgeClient

with BridgeClient(token="YOUR_TOKEN") as bridge:
    state = bridge.snapshot()
    print(state["ready"], state["cash"])
    print(bridge.upgrades())

The client supports state reads, activity reads and subscriptions, explicit single-stock activity-focus controls, trades, upgrade purchases, and auto-action controls. Activity focus can be set with set_human_activity_focus(stock_id) and cleared with clear_human_activity_focus(); the in-game overlay shows the active stock, and bridge-driven focus changes have a five-second minimum. See the bridge usage guide for the full API and its online behavior. Activity history reads page through only the samples the game currently retains in memory; they do not fetch older history from the game's server, and the bridge makes no guarantee about the retained history's total depth or time span.

Use offline_summary() to read the latest welcome-back summary captured during the current game session. The plugin captures it in memory before automatically closing the screen; set AutoCloseOfflineSummary = false in the BepInEx config to leave the screen open while retaining API access.
