Anything sent to https://api.chew.pro/* will be redirected to https://chew.pw/api/$1. This shouldn't matter as most handle redirects automatically, but if it doesn't, replace https://api.chew.pro with https://chew.pw/api.
You can tell these are in order of how I made them because the responses get better. This is all. Enjoy responsibly or I'll use CloudFlare to erase your homework.
