What is LangGraph?
A framework for building stateful, multi-step AI agent workflows as graphs. Built on top of LangChain for complex agentic applications.
Searching Google Reviews with LangGraph
This integration lets your LangGraph agent search Google Reviews in real time via the Scavio API. The agent gets back structured JSON with review text, star rating, reviewer name, review date — ready for reasoning and decision-making.
Setup
Bash
pip install langgraph langchain-scavio langchain-openaiCode Example
Here is a complete LangGraph agent that searches Google Reviews using Scavio:
Python
from langgraph.prebuilt import create_react_agent
from langchain_scavio import ScavioSearch
from langchain_openai import ChatOpenAI
tool = ScavioSearch(api_key="your_scavio_api_key")
llm = ChatOpenAI(model="gpt-4o")
agent = create_react_agent(llm, [tool])
result = agent.invoke({
"messages": [{"role": "user", "content": "Search Google Reviews for Blue Bottle Coffee San Francisco reviews"}]
})
print(result["messages"][-1].content)Full Working Example
