Steam (Wikipedia) is a video game digital distribution service and storefront developed by Valve Corporation. It provides game updates automatically for Valve’s games, and expanded to distributing third-party titles. Steam offers various features, like game server matchmaking with Valve Anti-Cheat measures, social networking, and game streaming services.
Steam is the ultimate destination for playing, discussing, and creating games.
Steam toolkit has two tools:
  • Game Details
  • Recommended Games
This guide provides a walkthrough of using Steam API with LangChain to retrieve Steam game recommendations based on your current Steam Game Inventory or to gather information regarding some Steam Games which you provide.

​
Setting up

We have to install two python libraries.

​
Imports

%pip install -qU python-steam-api python-decouple steamspypi

Note: you may need to restart the kernel to use updated packages.

​
Assign Environmental Variables

To use this toolkit, please have your OpenAI API Key, Steam API key (from here) and your own SteamID handy. Once you have received a Steam API Key, you can input it as an environmental variable below. The toolkit will read the “STEAM_KEY” API Key as an environmental variable to authenticate you so please set them here. You will also need to set your “OPENAI_API_KEY” and your “STEAM_ID”. 
import os

os.environ["STEAM_KEY"] = ""
os.environ["STEAM_ID"] = ""
os.environ["OPENAI_API_KEY"] = ""

​
Initialization

Initialize the LLM, SteamWebAPIWrapper, SteamToolkit and most importantly the langchain agent to process your query!

​
Example

from langchain_community.agent_toolkits.steam.toolkit import SteamToolkit
from langchain_community.utilities.steam import SteamWebAPIWrapper

steam = SteamWebAPIWrapper()
tools = [steam.run]

from langchain.agents import create_agent

agent = create_agent("openai:gpt-4.1-mini", tools)

events = agent.stream(
    {"messages": [("user", "can you give the information about the game Terraria?")]},
    stream_mode="values",
)
for event in events:
    event["messages"][-1].pretty_print()
