Overview

Integration details

Class	Package	Serializable	JS support
SmartScraperTool	langchain-scrapegraph	✅	❌

LocalScraperTool	langchain-scrapegraph	✅	❌
GetCreditsTool	langchain-scrapegraph	✅	❌

Tool features

Tool	Purpose	Input	Output
SmartScraperTool	Extract structured data from websites	URL + prompt	JSON
MarkdownifyTool	Convert webpages to markdown	URL	Markdown text
LocalScraperTool	Extract data from HTML content	HTML + prompt	JSON
GetCreditsTool	Check API credits	None	Credit info

Setup

The integration requires the following packages:

%pip install --quiet -U langchain-scrapegraph

Note: you may need to restart the kernel to use updated packages.

Credentials

You'll need a ScrapeGraph AI API key to use these tools. Get one at scrapegraphai.com.

import getpass
import os

if not os.environ.get("SGAI_API_KEY"):
    os.environ["SGAI_API_KEY"] = getpass.getpass("ScrapeGraph AI API key:\n")

It's also helpful (but not needed) to set up LangSmith for best-in-class observability:

os.environ["LANGCHAIN_TRACING_V2"] = "true"
os.environ["LANGCHAIN_API_KEY"] = getpass.getpass()

Instantiation

Here we show how to instantiate instances of the ScrapeGraph tools:

from langchain_scrapegraph.tools import (
    GetCreditsTool,
    LocalScraperTool,
    MarkdownifyTool,
    SmartScraperTool,
)

smartscraper = SmartScraperTool()
markdownify = MarkdownifyTool()
localscraper = LocalScraperTool()
credits = GetCreditsTool()

Invocation

Invoke directly with args

Let's try each tool individually:

# SmartScraper
result = smartscraper.invoke(
    {
        "user_prompt": "Extract the company name and description",
        "website_url": "https://scrapegraphai.com",
    }
)
print("SmartScraper Result:", result)

# Markdownify
markdown = markdownify.invoke({"website_url": "https://scrapegraphai.com"})
print("\nMarkdownify Result (first 200 chars):", markdown[:200])

local_html = """
<html>
    <body>
        <h1>Company Name</h1>
        <p>We are a technology company focused on AI solutions.</p>
        <div class="contact">
            <p>Email: contact@example.com</p>
            <p>Phone: (555) 123-4567</p>
        </div>
    </body>
</html>
"""

# LocalScraper
result_local = localscraper.invoke(
    {
        "user_prompt": "Make a summary of the webpage and extract the email and phone number",
        "website_html": local_html,
    }
)
print("LocalScraper Result:", result_local)

# Check credits
credits_info = credits.invoke({})
print("\nCredits Info:", credits_info)

SmartScraper Result: {'company_name': 'ScrapeGraphAI', 'description': "ScrapeGraphAI is a powerful AI web scraping tool that turns entire websites into clean, structured data through a simple API. It's designed to help developers and AI companies extract valuable data from websites efficiently and transform it into formats that are ready for use in LLM applications and data analysis."}

LocalScraper Result: {'company_name': 'Company Name', 'description': 'We are a technology company focused on AI solutions.', 'contact': {'email': 'contact@example.com', 'phone': '(555) 123-4567'}}

Credits Info: {'remaining_credits': 49679, 'total_credits_used': 914}

Invoke with ToolCall

We can also invoke the tool with a model-generated ToolCall:

model_generated_tool_call = {
    "args": {
        "user_prompt": "Extract the main heading and description",
        "website_url": "https://scrapegraphai.com",
    },
    "id": "1",
    "name": smartscraper.name,
    "type": "tool_call",
}
smartscraper.invoke(model_generated_tool_call)

ToolMessage(content='{"main_heading": "Get the data you need from any website", "description": "Easily extract and gather information with just a few lines of code with a simple api. Turn websites into clean and usable structured data."}', name='SmartScraper', tool_call_id='1')
