axiom-langchain

Axiom Stack Oracle tool for LangChain AI agents — plug-and-play M2M Real World Asset data purchasing on Solana.

pip install axiom-langchain

Quick start

from axiom_langchain import AxiomValuationTool
from langchain.agents import create_agent
from langchain_openai import ChatOpenAI

tool = AxiomValuationTool()
agent = create_agent(model="openai:gpt-4o", tools=[tool])
result = agent.invoke({"messages": [
    {"role": "user", "content": "What is the valuation for HAWTHORNE-001? Buy the data."}
]})

The tool autonomously:

1. Transfers 0.01 SOL to the Axiom Treasury on Solana
2. Confirms the transaction and captures the signature
3. Calls GET /api/v1/oracle/{asset_id}?tx_signature={sig}
4. Returns structured valuation data (consensus score, confidence, NOI, audit hash) to the LLM
