Simple API status badges.
To get colors, we record min and max response times, and find where yours sits in the range, and do some math (courtesy of @appellation) to figure out a color.
Firstly you need a route on your API that returns a successful status code (2xx or 3xx) and preferably does no logic. Then you can put the badge on your README.
