Readability Score is a simple tool for calculating the readability score of text. It returns the readability score based on various readability formulas.
The Text Readability Score API provides a simple, reliable way to integrate text readability score functionality into your applications. Built for developers who need production-ready text readability score capabilities without the complexity of building from scratch.
Quick Start
Using JavaScript
async function callTextReadabilityScoreAPI() {
try {
const requestBody = {
"text": "Western astrology is founded on the movements and relative positions of celestial bodies such as the Sun, Moon and planets, which are analysed by their movement through signs of the zodiac (twelve spatial divisions of the ecliptic) and by their aspects (based on geometric angles) relative to one another."
};
const response = await fetch('https://api.apiverve.com/v1/readabilityscore', {
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);
}
}
