3. AI Search as a Tool in Agents

from langchain_aisearchapi import AISearchTool, AISearchLLM
from langchain.agents import initialize_agent, AgentType

search_tool = AISearchTool(api_key="your-key")
llm = AISearchLLM(api_key="your-key")

agent = initialize_agent(
    tools=[search_tool],
    llm=llm,
    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
    verbose=True
)

result = agent.run("Find the latest SpaceX launch details")
