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 SERP Ads with LangGraph
This integration lets your LangGraph agent search Google SERP Ads in real time via the Scavio API. The agent gets back structured JSON with top_ads, bottom_ads, ad headlines, destination URLs -- 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 SERP Ads using Scavio:
Python
from langgraph.prebuilt import create_react_agent
from langchain_scavio import ScavioSearch
from langchain_openai import ChatOpenAI
tool = ScavioSearch(scavio_api_key="sk_live_your_key")
llm = ChatOpenAI(model="gpt-5.5")
agent = create_react_agent(llm, [tool])
result = agent.invoke({
"messages": [{"role": "user", "content": "Search Google SERP Ads for project management software"}]
})
print(result["messages"][-1].content)Full Working Example
