The following QR code style and color examples are the most common and widely used. Black and white QR codes give the highest amount of contrast between the dark and light data modules. This makes them easier for smart phone cameras to scan and read the data in a more reliable manner.
If you would prefer to customize the color of your QR codes our API can do that for you as well. Just use the color parameter in our crypto QR code generator's API. Detailed documentation below.
A GET request is a type of HTTP method for requesting information or resources from a website. GET is also one of the most common HTTP methods today.
Note in this example below that the query string (parameter/value pairs) is sent in the URL of a GET request.
We've made things easy by including example GET request URL's for our QR code API below. All you have to do is change the values to reflect your own required QR code needs. Refer to the parameter names and their possible values using the charts below.
For more advanced webmasters you may want to dynamically generate wallet addresses in place of the GET requests crypto wallet address value using your favorite programming language.
The address parameter is the public crypto wallet address that you would like to convert into a QR code format. Make sure the crypto address you add to the GET request matches the crypto style parameter above.
If the address and style do not match a default non QR code image will be returned. If you see the following image returned when making an API request check for missing required parameters or parameter errors.

The amount parameter is used to automatically set the amount of cryptocurrency you wish to send or receive. This feature is handy if you are requesting payments for goods or services.
When you or someone scans the QR code it will fill in the crypto address as well as the amount field, streamlining the sending or receiving process.
In the following example we would like to include the set amount of 0.0005 BTC with address 1M5m1DuGw4Wyq1Nf8sfoKRM6uA4oREzpCX in a QR code format.
Each cryptocurrency amount is rounded to their nearest pre configured decimal place. Here is a chart showing each crypto and the set decimal place they function with.
This setting works in conjunction with the amount parameter. When a fiat currency is set the amount entered will be fiat not crypto.
Then when the QR code is requested via our API it will automatically convert the fiat amount into the corresponding cryptocurrency amount based on the current market rates.
Consider the following example. This API request will include the set amount of $100 USD worth of BTC with address 1M5m1DuGw4Wyq1Nf8sfoKRM6uA4oREzpCX in a QR code format.
The color parameter will change the default black and white QR code to any one of the following shown below. If the color is not set the default will be black with a white background or parameter 1.
The URI prefix by default is always on so it's not necessary to set the prefix in the GET request if you actually want the URI added to your crypto wallet addresses. If you would like to remove the URI prefix from your QR codes just set the prefix parameter to off.
The border parameter gives you the option of adding a border to your crypto QR code. Below are the current border designs available. The default is no border when the parameter is not set.
Simply replace the border parameter with the corresponding border style type number shown in the table above to customize your QR codes. Plus use this in conjunction with the QR color parameter for even more of a verity of styles.
The following URL is an example API request which includes a red textured border and a red QR code.
Send a GET request in the following form to get a crypto QR code graphic in PNG format (to generate a QR code).
Test it within your browser by requesting the following URL example.
Now you can easily embed the QR code in your (X)HTML documents by using the img tag. Example code shown below.
300 by 300 pixels is the base image size. You can make the image smaller by simply changing the dimensions of the (X)HTML img tag while still maintaining the image resolution. Just make sure both height and width are the same dimensions.
Sample image output from (X)HTML code shown above using an API request.
