ScrapeGraphAI streamlines the process by combining advanced scraping techniques with schema validation, ensuring accurate and structured data extraction.

Python Example


python
from scrapegraph_py import Client
from scrapegraph_py.logger import sgai_logger
from pydantic import BaseModel, Field

# Set logging to INFO for detailed output
sgai_logger.set_logging(level="INFO")

# Initialize the client with your API key
sgai_client = Client(api_key="sgai-********************")

# Define the schema for the product listing
class ProductListingSchema(BaseModel):
    KeyboardName: str = Field(..., description="The name of the keyboard")
    Price: float = Field(..., description="The price of the keyboard")

# Send a SmartScraper request to Amazon's search page for keyboards
response = sgai_client.smartscraper(
    website_url="https://www.amazon.it/s?k=keyboards&__mk_it_IT=ÅMÅŽÕÑ&crid=MMF6T1GWDMO6&sprefix=keyboars%2Caps%2C119&ref=nb_sb_noss_2",
    user_prompt="Extract the KeyboardName and Price from the product listings",
    output_schema=ProductListingSchema
)

# Print the response details
print(f"Request ID: {response['request_id']}")
print(f"Result: {response['result']}")

sgai_client.close()

JavaScript Example with Zod


javascript
import { Client } from 'scrapegraph-js';
import { z } from "zod";

// Define the schema using Zod
const productListingSchema = z.object({
  /** The name of the keyboard */
  KeyboardName: z.string(),
  /** The price of the keyboard */
  Price: z.number(),
});

type ProductListingSchema = z.infer<typeof productListingSchema>;

// Initialize the client
const sgai_client = new Client("sgai-********************");

try {
  const response = await sgai_client.smartscraper({
    websiteUrl: "https://www.amazon.it/s?k=keyboards&__mk_it_IT=ÅMÅŽÕÑ&crid=MMF6T1GWDMO6&sprefix=keyboars%2Caps%2C119&ref=nb_sb_noss_2",
    userPrompt: "Extract the KeyboardName and Price from the product listings",
    outputSchema: productListingSchema
  });

  console.log('Request ID:', response.requestId);
  console.log('Result:', response.result);
} catch (error) {
  console.error(error);
} finally {
  sgai_client.close();
}
