Example: Extracting Keyboard Prices with LlamaIndex and ScrapeGraphAI

Here's an example implementation that combines LlamaIndex and ScrapeGraphAI to extract keyboard prices from an e-commerce website:

python
import os
from llama_index.core.tools import FunctionTool
from llama_index.llms.openai import OpenAI
from llama_index.core.agent import ReActAgent

def scrapegraph_tool_invocation(prompt, url):
    from llama_index.tools.scrapegraph.base import ScrapegraphToolSpec

    scrapegraph_tool = ScrapegraphToolSpec()
    response = scrapegraph_tool.scrapegraph_smartscraper(
        prompt=prompt,
        url=url,
        api_key=os.getenv("SGAI_API_KEY"),
    )
    return response

# Fetch API keys
openai_api_key = os.getenv("OPENAI_API_KEY")
if not openai_api_key:
    raise EnvironmentError("OpenAI API key not found. Set the OPENAI_API_KEY environment variable.")

scrapegraph_api_key = os.getenv("SGAI_API_KEY")
if not scrapegraph_api_key:
    raise EnvironmentError("ScrapeGraph API key not found. Set the SGAI_API_KEY environment variable.")

# Initialize tools and agent
scrape_tool = FunctionTool.from_defaults(fn=scrapegraph_tool_invocation)
llm = OpenAI(model="gpt-4", api_key=openai_api_key)
agent = ReActAgent.from_tools([scrape_tool], llm=llm, verbose=True)

# Extract product data from a website
link = "https://www.ebay.com/sch/i.html?_from=R40&_trksid=p4432023.m570.l1313&_nkw=keyboards&_sacat=0"
res = agent.chat(f"Extract me all the keyboard names and prices from the following website: {link}")
print(res)
