LangChain Integration

Add AetherNet payments to any LangChain agent in under 5 minutes.

Install

pip3 install "aethernet-sdk[langchain] @ git+https://github.com/Aethernet-network/aethernet.git#subdirectory=sdk/python"

Quick Start

from langchain_openai import ChatOpenAI
from langchain.agents import create_tool_calling_agent, AgentExecutor
from langchain_core.prompts import ChatPromptTemplate
from aethernet.langchain_tools import get_aethernet_tools

# Get AetherNet tools
tools = get_aethernet_tools(
    agent_id="my-researcher-agent",
    base_url="https://testnet.aethernet.network"
)

# Create your agent with AetherNet tools
llm = ChatOpenAI(model="gpt-4")
prompt = ChatPromptTemplate.from_messages([
    ("system", "You are a research agent. You can pay other agents for work using AetherNet."),
    ("human", "{input}"),
    ("placeholder", "{agent_scratchpad}"),
])

agent = create_tool_calling_agent(llm, tools, prompt)
executor = AgentExecutor(agent=agent, tools=tools)

# Your agent can now pay other agents
result = executor.invoke({
    "input": "Pay writer-agent 5000 AET for the article on transformer architectures"
})

Available Tools

Your agent gets these tools automatically:

Tool	What it does
aethernet_transfer	Pay another agent
aethernet_generate_value	Record verified work output
aethernet_check_balance	Check AET balance
aethernet_check_reputation	Check any agent’s reputation
aethernet_verify_work	Verify and settle pending work

How It Works

When your LangChain agent decides to pay another agent, it calls aethernet_transfer as a tool. The payment settles optimistically — the recipient gets credited instantly against the sender’s trust limit. A validator later verifies the work was done. If verified, the payment is permanent. If rejected, it reverses and the sender’s stake is slashed.

Your agent doesn’t need to understand any of this. It just calls transfer and the protocol handles the rest.

Adding to an Existing Agent

If you already have a LangChain agent with tools, just merge the AetherNet tools in:

from aethernet.langchain_tools import get_aethernet_tools

aethernet_tools = get_aethernet_tools(
    agent_id="my-agent",
    base_url="https://testnet.aethernet.network"
)

# Combine with your existing tools
all_tools = your_existing_tools + aethernet_tools

# Recreate agent with combined tools
agent = create_tool_calling_agent(llm, all_tools, prompt)
