Tool features

Tool	Purpose	Input	Output
SmartScraperTool	Extract structured data from websites	URL + prompt	JSON
SmartCrawlerTool	Extract data from multiple pages with crawling	URL + prompt + crawl options	JSON
MarkdownifyTool	Convert webpages to markdown	URL	Markdown text

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["LANGSMITH_TRACING"] = "true"
os.environ["LANGSMITH_API_KEY"] = getpass.getpass()

Instantiation

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

from scrapegraph_py.logger import sgai_logger
import json

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

sgai_logger.set_logging(level="INFO")

smartscraper = SmartScraperTool()
smartcrawler = SmartCrawlerTool()
markdownify = MarkdownifyTool()
credits = GetCreditsTool()

Invocation

Invoke directly with args

Let’s try each tool individually:

SmartCrawler Tool

The SmartCrawlerTool allows you to crawl multiple pages from a website and extract structured data with advanced crawling options like depth control, page limits, and domain restrictions.

# 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])

# SmartCrawler
url = "https://scrapegraphai.com/"
prompt = (
    "What does the company do? and I need text content from their privacy and terms"
)

# Use the tool with crawling parameters
result_crawler = smartcrawler.invoke(
    {
        "url": url,
        "prompt": prompt,
        "cache_website": True,
        "depth": 2,
        "max_pages": 2,
        "same_domain_only": True,
    }
)

print("\nSmartCrawler Result:")
print(json.dumps(result_crawler, indent=2))

# 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."}

# SmartCrawler example
from scrapegraph_py.logger import sgai_logger
import json

from langchain_scrapegraph.tools import SmartCrawlerTool

sgai_logger.set_logging(level="INFO")

# Will automatically get SGAI_API_KEY from environment
tool = SmartCrawlerTool()

# Example based on the provided code snippet
url = "https://scrapegraphai.com/"
prompt = (
    "What does the company do? and I need text content from their privacy and terms"
)

# Use the tool with crawling parameters
result = tool.invoke(
    {
        "url": url,
        "prompt": prompt,
        "cache_website": True,
        "depth": 2,
        "max_pages": 2,
        "same_domain_only": True,
    }
)

print(json.dumps(result, indent=2))

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')

Chaining

Let’s use our tools with an LLM to analyze a website:

# | output: false
# | echo: false

# %pip install -qU langchain langchain-openai
from langchain.chat_models import init_chat_model

llm = init_chat_model(model="gpt-4o", model_provider="openai")

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

from langchain_core.prompts import ChatPromptTemplate
from langchain_core.runnables import RunnableConfig, chain

prompt = ChatPromptTemplate(
    [
        (
            "system",
            "You are a helpful assistant that can use tools to extract structured information from websites.",
        ),
        ("human", "{user_input}"),
        ("placeholder", "{messages}"),
    ]
)

llm_with_tools = llm.bind_tools([smartscraper], tool_choice=smartscraper.name)
llm_chain = prompt | llm_with_tools


@chain
def tool_chain(user_input: str, config: RunnableConfig):
    input_ = {"user_input": user_input}
    ai_msg = llm_chain.invoke(input_, config=config)
    tool_msgs = smartscraper.batch(ai_msg.tool_calls, config=config)
    return llm_chain.invoke({**input_, "messages": [ai_msg, *tool_msgs]}, config=config)


tool_chain.invoke(
    "What does ScrapeGraph AI do? Extract this information from their website https://scrapegraphai.com"
)
