LlamaIndex

Leverage the LlamaIndex integration with the Oxylabs Web Scraper API to easily ingest online content and build LLM-driven workflows.

The LlamaIndex integration with the Oxylabs Web Scraper API enables you to scrape and process web data through an LLM (Large Language Model) in the same workflow.

Overview

LlamaIndex is a data framework designed for building LLM applications with external data sources. Use it with Oxylabs Web Scraper API to:

• Scrape structured data without handling CAPTCHAs, IP blocks, or JS rendering

• Process results with an LLM in the same pipeline

• Build end-to-end workflows from extraction to AI-powered output

Getting started

Create your API user credentials: sign up for a free trial or purchase the product in the Oxylabs dashboard to create your API user credentials (USERNAME and PASSWORD).

If you need more than one API user for your account, please contact our customer support or message our 24/7 live chat support.

Environment setup

In this guide we will use Python programming language. Install the required libraries using pip:

pip install -qU llama-index llama-index-readers-oxylabs llama-index-readers-web

Create a .env file in your project directory with your Oxylabs Web Scraper API credentials and OpenAI API key:

OXYLABS_USERNAME=your_API_username
OXYLABS_PASSWORD=your_API_password
OPENAI_API_KEY=your-openai-key

Load these environment variables in your Python script:

import os
from dotenv import load_dotenv

load_dotenv()

Integration methods

There are two ways to access web content via Web Scraper API in LlamaIndex:

Oxylabs Reader

The llama-index-readers-oxylabs module contains specific classes that enable you to scrape data from various sources:

API Data Source	Reader Class
Google Web Search	OxylabsGoogleSearchReader
Google Search Ads	OxylabsGoogleAdsReader
Amazon Product	OxylabsAmazonProductReader
Amazon Search	OxylabsAmazonSearchReader
Amazon Reviews	OxylabsAmazonReviewsReader
YouTube Transcript	OxylabsYoutubeTranscriptReader

For example, you can extract Google search results:

import os
from dotenv import load_dotenv
from llama_index.readers.oxylabs import OxylabsGoogleSearchReader

load_dotenv()
reader = OxylabsGoogleSearchReader(
    os.getenv('OXYLABS_USERNAME'), os.getenv('OXYLABS_PASSWORD')
)
results = reader.load_data({
    'query': 'best pancake recipe',
    'parse': True
})
print(results[0].text)

Oxylabs Web Reader

With the OxylabsWebReader class, you can extract data from any URL:

import os
from dotenv import load_dotenv
from llama_index.readers.web import OxylabsWebReader

load_dotenv()
reader = OxylabsWebReader(
    os.getenv('OXYLABS_USERNAME'), os.getenv('OXYLABS_PASSWORD')
)
results = reader.load_data(
    [
        'https://sandbox.oxylabs.io/products/1',
        'https://sandbox.oxylabs.io/products/2'
    ]
)
for result in results:
    print(result.text + '\n')

Building a basic AI search agent

Below is an example of a simple AI agent that can search Google and answer questions:

import os
import asyncio
from dotenv import load_dotenv
from llama_index.readers.oxylabs import OxylabsGoogleSearchReader
from llama_index.core.agent.workflow import FunctionAgent
from llama_index.llms.openai import OpenAI

load_dotenv()
reader = OxylabsGoogleSearchReader(
    os.getenv('OXYLABS_USERNAME'), os.getenv('OXYLABS_PASSWORD')
)

def web_search(query: str) -> str:
    results = reader.load_data({'query': query, 'parse': True})
    return results[0].text

agent = FunctionAgent(
    tools=[web_search],
    llm=OpenAI(model='gpt-4o-mini'),
    max_function_calls=1,
    system_prompt=(
        'Craft a short Google search query to use with the `web_search` tool. '
        'Analyze the most relevant results and answer the question.'
    )
)

async def main():
    response = await agent.run('How did DeepSeek affect the stock market?')
    print(response)

if __name__ == '__main__':
    asyncio.run(main())

Advanced configuration

Handling dynamic content

The Web Scraper API can handle JavaScript rendering:

reader = OxylabsWebReader(
    os.getenv('OXYLABS_USERNAME'), os.getenv('OXYLABS_PASSWORD')
)

results = reader.load_data(
    [
        'https://quotes.toscrape.com/js/'
    ],
    {'render': 'html'}
)

Setting user agent type

You can specify different user agents:

reader = OxylabsWebReader(
    os.getenv('OXYLABS_USERNAME'), os.getenv('OXYLABS_PASSWORD')
)

results = reader.load_data(
    [
        'https://sandbox.oxylabs.io/products/1'
    ],
    {'user_agent_type': 'mobile'}
)

Using target-specific parameters

Many target-specific scrapers support additional parameters:

reader = OxylabsGoogleSearchReader(
    os.getenv('OXYLABS_USERNAME'),
    os.getenv('OXYLABS_PASSWORD')
)
results = reader.load_data({
    'query': 'iphone',
    'parse': True,
    'domain': 'com',
    'start_page': 2,
    'pages': 3
})

Creating vector indices

LlamaIndex is particularly useful for building vector indices from web content:

import os
from dotenv import load_dotenv
from llama_index.readers.web import OxylabsWebReader
from llama_index.core import Settings, VectorStoreIndex
from llama_index.llms.openai import OpenAI

load_dotenv()
reader = OxylabsWebReader(
    os.getenv('OXYLABS_USERNAME'), os.getenv('OXYLABS_PASSWORD')
)
documents = reader.load_data([
    'https://sandbox.oxylabs.io/products/1',
    'https://sandbox.oxylabs.io/products/2'
])

# Configure LlamaIndex settings
Settings.llm = OpenAI(model='gpt-4o-mini')

# Create an index
index = VectorStoreIndex.from_documents(documents)

# Query the index
query_engine = index.as_query_engine()
response = query_engine.query('What is the main topic of these pages?')
print(response)
