Currency API: How to Easily Get Exchange Rates with JavaScript

Any business website with international prospects is eventually going to navigate the elastic world of currency exchange rates. Never fear — we’ve got you covered with a simple, effective currency exchange API that requires only the three-digit source & destination currency codes to provide the necessary exchange data.

With the instructions provided below, you can easily take advantage of this API using JavaScript. If you’re looking for code in a different programming language instead, we’ve got that covered too — visit the Cloudmersive API Console to find the necessary code snippets conveniently available in over a dozen of the most common programming languages (including Java, Python, Node.js, C#, and more).

To install the jQuery library, run the below command:

bower install jquery

After that, just include the currency exchange function, supply our Cloudmersive API key (obtainable by registering for a free account on our website, Home — Cloudmersive APIs), and you’re good to go:

var settings = {
"url": "<string>/to/<string>",
"method": "POST",
"timeout": 0,
"headers": {
$.ajax(settings).done(function (response) {
