I Created Another On this Day API
There are multiple “On this Day” APIs built on top of Wikipedia but I created yet another one. This API can be used to retrieve birth, deaths, and events for any given day of the year.
The reason for building this was that I wanted something stable with support for things like Cross-Origin-Requests and SSL. The need wasn’t actually mine. A friend of mine sees the potential of “On this Day” information as a possible delighter in everyday contexts and I offered to help.
