Keyword Extractor API

Keyword Extractor is a keyword extraction API that scans raw text or live webpage URLs to extract key terms and their frequencies. It returns up to 50 unique keywords, occurrence counts, total keyword volume, and the top five terms with their percentage share.

The Keyword Extractor API provides a simple, reliable way to integrate keyword extractor functionality into your applications. Built for developers who need production-ready keyword extractor capabilities without the complexity of building from scratch.

Quick Start

Using JavaScript

async function callKeywordExtractorAPI() {
    try {
        const requestBody = {
    "text": "Machine learning is a subset of artificial intelligence that enables systems to learn from data. Deep learning uses neural networks to process complex patterns in data."
};

        const response = await fetch('https://api.apiverve.com/v1/keywordextractor', {
            method: 'POST',
            headers: {
                'x-api-key': 'YOUR_API_KEY_HERE',
                'Content-Type': 'application/json'
            },
            body: JSON.stringify(requestBody)
        });

        const data = await response.json();
        console.log(data);
    } catch (error) {
        console.error('Error:', error);
    }
}

callKeywordExtractorAPI();
