Exploring Math.tools API with JavaScript

Math.tools provides a free and open API for developers to use in their projects. In this blog post, we'll explore some of the available endpoints and provide example code in JavaScript.

Getting Started

Before we begin, you'll need an API key. You can sign up for one for free on the Math.tools API documentation page.

To use the API in your JavaScript code, you will need to make HTTP requests to the API's endpoints using a library like Axios or Fetch.

Example Code

Here is an example of how to make a request to the sqrt endpoint using Axios:

const axios = require('axios');

const BASE_URL = 'https://math.tools/api/numbers';
const API_KEY = '<insert your API key here>';

const number = 16;

axios.get(`${BASE_URL}/sqrt/${number}?apikey=${API_KEY}`)
  .then(response => {
    console.log(response.data.result);
  })
  .catch(error => {
    console.log(error.response.data.error);
  });

Here is the same request using Fetch:

const BASE_URL = 'https://math.tools/api/numbers';
const API_KEY = '<insert your API key here>';

const number = 16;

fetch(`${BASE_URL}/sqrt/${number}?apikey=${API_KEY}`)
  .then(response => response.json())
  .then(json => {
    console.log(json.result);
  })
  .catch(error => {
    console.log(error.message);
  });

Note that in both examples, we need to include our API key in the request URL as a query parameter.

Available Endpoints
