Text Readability Score API

Readability Score is a simple tool for calculating the readability score of text. It returns the readability score based on various readability formulas.

This is a Javascript Wrapper for the Text Readability Score API

Installation

Using npm:

npm install @apiverve/readabilityscore

Using yarn:

yarn add @apiverve/readabilityscore

Configuration

Before using the Text Readability Score API client, you have to setup your account and obtain your API Key. You can get it by signing up at https://apiverve.com

Quick Start

Get started with the Quick Start Guide

The Text Readability Score API documentation is found here: https://docs.apiverve.com/ref/readabilityscore. You can find parameters, example responses, and status codes documented here.

Setup

const readabilityscoreAPI = require('@apiverve/readabilityscore');
const api = new readabilityscoreAPI({
    api_key: '[YOUR_API_KEY]'
});

Usage

Perform Request

Using the API is simple. All you have to do is make a request. The API will return a response with the data you requested.

var query = {
  "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."
};

api.execute(query, function (error, data) {
    if (error) {
        return console.error(error);
    } else {
        console.log(data);
    }
});

Using Promises

You can also use promises to make requests. The API returns a promise that you can use to handle the response.

var query = {
  "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."
};

api.execute(query)
    .then(data => {
        console.log(data);
    })
    .catch(error => {
        console.error(error);
    });

Using Async/Await

You can also use async/await to make requests. The API returns a promise that you can use to handle the response.

async function makeRequest() {
    var query = {
  "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."
};

    try {
        const data = await api.execute(query);
        console.log(data);
    } catch (error) {
        console.error(error);
    }
}
