SearchApi Integration

[dremeika]

Based on the customers' requests for native langchain integration, SearchApi is ready to invest in AI and LLM space, especially in open-source development.

• This is our initial PR and later we want to improve it based on customers' and langchain users' feedback. Most likely changes will affect how the final results string is being built.
• We are creating similar native integration in Python and JavaScript.
• The next plan is to integrate into Java, Ruby, Go, and others.
• Feel free to assign @SebastjanPrachovskij as a main reviewer for any SearchApi-related searches. We will be glad to help and support langchain development.

Usage

from langchain.utilities import SearchApiAPIWrapper
from langchain.llms.openai import OpenAI
from langchain.agents import initialize_agent, Tool
from langchain.agents import AgentType

import os
os.environ["OPENAI_API_KEY"] = ""
os.environ["SEARCHAPI_API_KEY"] = ""

llm = OpenAI(temperature=0)
search = SearchApiAPIWrapper()
tools = [
    Tool(
        name="Intermediate Answer",
        func=search.run,
        description="useful for when you need to ask with search"
    )
]

self_ask_with_search = initialize_agent(tools, llm, agent=AgentType.SELF_ASK_WITH_SEARCH, verbose=True)
self_ask_with_search.run("Who lived longer: Plato, Socrates, or Aristotle?")
