README

Text Similarity compares two text strings and calculates their percentage match score. It returns case-insensitive and case-sensitive similarity scores plus the count and proportion of differing words.

The Text Similarity API provides a simple, reliable way to integrate text similarity functionality into your applications. Built for developers who need production-ready text similarity capabilities without the complexity of building from scratch.

Quick Start

Using JavaScript

async function callTextSimilarityAPI() {
    try {
        const requestBody = {
    "text1": "I'm so excited that tomorrow is going to be sunny! Can't wait!",
    "text2": "We're pretty excited about the weather tomorrow. It's going to be sunny!"
};

        const response = await fetch('https://api.apiverve.com/v1/textsimilarity', {
            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);
    }
}

callTextSimilarityAPI();
