What is LangChain?
The most popular framework for building LLM-powered applications. Provides chains, agents, and tools for composing AI workflows.
Searching Amazon with LangChain
This integration lets your LangChain agent search Amazon in real time via the Scavio API. The agent gets back structured JSON with product listings, prices, ratings, review counts — ready for reasoning and decision-making.
Setup
Bash
pip install langchain langchain-scavio langchain-openaiCode Example
Here is a complete LangChain agent that searches Amazon using Scavio:
Python
from langchain_scavio import ScavioSearch
from langchain_openai import ChatOpenAI
from langchain.agents import create_tool_calling_agent, AgentExecutor
from langchain_core.prompts import ChatPromptTemplate
# Initialize the Scavio search tool
tool = ScavioSearch(api_key="your_scavio_api_key")
# Create an agent with the tool
llm = ChatOpenAI(model="gpt-4o")
prompt = ChatPromptTemplate.from_messages([
("system", "You are a helpful research assistant."),
("human", "{input}"),
("placeholder", "{agent_scratchpad}"),
])
agent = create_tool_calling_agent(llm, [tool], prompt)
executor = AgentExecutor(agent=agent, tools=[tool])
# Search specifically on Amazon
result = agent.invoke({"input": "Search Amazon for mechanical keyboard"})
print(result["output"])Full Working Example
