Build comprehensive knowledge bases for retrieval-augmented generation. Power your AI chatbots and assistants with structured web content.
Retrieval-augmented generation systems are only as good as their knowledge base. Building a comprehensive, up-to-date corpus requires efficient web content extraction.
Static documents become outdated quickly. You need automated collection of fresh content from documentation sites, knowledge bases, and authoritative sources.
Everything you need for RAG systems
Extract main content without navigation, ads, or boilerplate.
Preserve document structure with headings and sections.
Extract specific information using natural language queries.
Maintain source URLs for citation and verification.
Build your RAG knowledge base
const axios = require('axios');
const API_KEY = 'your_api_key';
// Extract documentation content for RAG
const docUrl = 'https://docs.example.com/api/authentication';
const content = await axios.get('https://api.webscraping.ai/ai/fields', {
params: {
api_key: API_KEY,
url: docUrl,
fields: JSON.stringify({
title: 'Page title',
main_content: 'Main content text without navigation',
sections: 'Array of section headings and their content',
code_examples: 'Any code snippets on the page',
key_concepts: 'Key concepts or terms defined',
related_topics: 'Links to related documentation pages'
})
}
});
console.log(content.data);
// {
// "title": "API Authentication Guide",
// "main_content": "This guide covers authentication methods...",
// "sections": [
// {"heading": "API Keys", "content": "API keys are..."},
// {"heading": "OAuth 2.0", "content": "For OAuth flow..."}
// ],
// "code_examples": ["curl -H 'Authorization: Bearer...'"],
// "key_concepts": ["API key", "Bearer token", "OAuth scope"],
// "related_topics": ["/docs/rate-limits", "/docs/errors"]
// }
// Generate a summary for the knowledge base
const summary = await axios.get('https://api.webscraping.ai/ai/question', {
params: {
api_key: API_KEY,
url: docUrl,
question: 'Provide a 2-3 sentence summary of this page suitable for a knowledge base index.'
}
});
