Quick Start

Using JavaScript

async function callColorSimilarityCalculatorAPI() {
    try {
        const params = new URLSearchParams({
            color1: 'FF5733',
            color2: 'FF6B47'
        });

        const response = await fetch(`https://api.apiverve.com/v1/colorsimilarity?${params}`, {
            method: 'GET',
            headers: {
                'x-api-key': 'YOUR_API_KEY_HERE'
            }
        });

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

callColorSimilarityCalculatorAPI();
