How to Use Icotar

Icotar images may be requested just like a normal image. Our HTTP-API is based on the system built by the fine folks at Gravatar.

Base Request

The most basic image request URL looks like this:


Where :hash is replaced with anything you like. But don't use any sensitive or personal data here! For example, here is a base URL:


File Types

All avatars are served as SVG files by default. If you require a file-type extension then you can add an optional .svg extension to that URL:


Icotar also supports PNG files:



By default, PNG images are presented at 80px by 80px if no size parameter is supplied. You may request a specific image size, which will be dynamically delivered from Icotar by using the s= or size= parameter and passing a single pixel dimension (since Icotars are square):


You may request images anywhere from 1px up to 1024px.

Secure Requests

All URL requests should start with HTTPS.
