Crypto Icon API Service

Originally posted on Medium.

We’ve just released (and open sourced!) the web service we built for serving the cryptocurrency icons maintained by the Cryptocurrency Icons project.

The service was originally built for use in Quids for Mac to avoid bundling every icon with the client and having to make a new release everytime we supported a new currency. Instead, we use this service to dynamically accept the SVG source and render a PNG, using any of the included icon styles provided and at any size we need.

We have also released the Swift library we use in Quids to build the URLs.

The service is completely free to use but is provided “as is”. If you wish to guarantee uptime (like we do for Quids), I recommend deploying your own instance. The Github README has a Heroku button to make deploying your own instance of the service really simple.
