Free QR Code API - The Easiest QR Code API In Existence

Introduction

Welcome to the latest version of the QR Code Generator API. Turn any text or URL into a crisp, fully-customisable QR code from a single GET request.

There's no SDK to install and no authentication flow beyond passing your API key in the request. If you can make an HTTP GET request, you can use QRCODER.

100 requests per 24 hours for FREE — no payment details required. Need more? See pricing.

Step 1 — Get an API key

Use the form below to create a quick account. We'll email you the API key you need to access the API, so make sure your address is correct!

Check your spam folder for this email! It sometimes lands there.

Step 2 — Make a request

Using the key from your email, build a GET request. Send your API key with every request to get the QR code returned. Here it is in four flavours:

example-1.phpphp

<?php
$key  = "YOUR-API-KEY";      // your unique api key
$text = "Hello World!";     // what to turn into a QR code

// make sure you urlencode the text part to be safe!
$url = "https://www.qrcoder.co.uk/api/v4/?key=" . $key
     . "&text=" . urlencode($text);

echo "<img src='" . $url . "' />";

<img src="https://www.qrcoder.co.uk/api/v4/?key=YOUR-API-KEY&text=Hello+World"
     alt="QR code" width="240" height="240" />

terminalbash

curl "https://www.qrcoder.co.uk/api/v4/?key=YOUR-API-KEY&text=Hello+World" \
  --output qr.png

qr.jsjavascript

const key  = "YOUR-API-KEY";
const text = encodeURIComponent("Hello World!");

const url = `https://www.qrcoder.co.uk/api/v4/?key=${key}&text=${text}`;
document.getElementById("qr").src = url;

Endpoint

All requests go to a single base URL. A minimal request needs just two parameters — your key and the URL-encoded text:

GET https://www.qrcoder.co.uk/api/v4/

minimal requesturl

https://www.qrcoder.co.uk/api/v4/?key=YOUR-API-KEY&text=Hello+World

A small but powerful set of parameters. Only key and text are required; everything else has a sensible default.
