AI Network is a layer 1 blockchain designed to accommodate large-scale AI models, utilizing a decentralized GPU network powered by the $AIN token, enriching AI-driven NFTs (AINFTs). The AINetwork Toolkit is a set of tools for interacting with the AINetwork Blockchain. These tools allow you to transfer AIN, read and write values, create apps, and set permissions for specific paths within the blockchain database.

​
Installing dependencies

Before using the AINetwork Toolkit, you need to install the ain-py package. You can install it with pip: 
%pip install --upgrade --quiet  ain-py langchain-community

​
Set environmental variables

You need to set the AIN_BLOCKCHAIN_ACCOUNT_PRIVATE_KEY environmental variable to your AIN Blockchain Account Private Key. 
import os

os.environ["AIN_BLOCKCHAIN_ACCOUNT_PRIVATE_KEY"] = ""

​
Get AIN Blockchain private key

import os

from ain.account import Account

if os.environ.get("AIN_BLOCKCHAIN_ACCOUNT_PRIVATE_KEY", None):
    account = Account(os.environ["AIN_BLOCKCHAIN_ACCOUNT_PRIVATE_KEY"])
else:
    account = Account.create()
    os.environ["AIN_BLOCKCHAIN_ACCOUNT_PRIVATE_KEY"] = account.private_key
    print(
        f"""
address: {account.address}
private_key: {account.private_key}
"""
    )
# IMPORTANT: If you plan to use this account in the future, make sure to save the
#  private key in a secure place. Losing access to your private key means losing
#  access to your account.

​
Initialize the AINetwork Toolkit

You can initialize the AINetwork Toolkit like this: 
from langchain_community.agent_toolkits.ainetwork.toolkit import AINetworkToolkit

toolkit = AINetworkToolkit()
tools = toolkit.get_tools()
address = tools[0].interface.wallet.defaultAccount.address

​
Initialize the Agent with the AINetwork Toolkit

You can initialize the agent with the AINetwork Toolkit like this: 
from langchain_openai import ChatOpenAI
from langgraph.prebuilt import create_react_agent

llm = ChatOpenAI(temperature=0)
agent = create_react_agent(model=llm, tools=tools)

​
Example Usage

Here are some examples of how you can use the agent with the AINetwork Toolkit:

​
Define App name to test

appName = f"langchain_demo_{address.lower()}"

​
Create an app in the AINetwork Blockchain database

print(
    agent.invoke(
        {
            "messages": f"Create an app in the AINetwork Blockchain database with the name {appName}"
        }
    )
)
