Background
URL shortening is a web technique that takes a URL and makes it shorter and more readable. Most often, the shortened URL relies on a unique code that is a combination of upper- and lower-case letters and numbers. For example:
https://bit.ly/32DDrrT
The problem with these codes is that they are error-prone when either typing them into a browser or relaying them by voice. For example:
“3, 2, big D, big D, little R, little R, big T.”
Far less error-prone — easier to relay and easier to type — are unique codes that are entirely numeric, for example:
https://go.wiz4.us/6491-3847-5745
go.wiz4.us
Finite Wisdom has developed its own URL shortener that uses all-numeric codes. As a security precaution, the shortener utilizes Google's Safe Browsing API in order to verify that the URL being shortened isn't malicious.
