Haven't tested it much (@Jackiexiao can you test it fully please?)
I only tested that it sends the right request. Sadly my used API is down so I couldn't get an actual response but the headers and everything seemed fine.
You might want to bump the version, build it and release it :)
You could store the default API in a variable but I was way too lazy and it shouldn't change too much + there is search and replace
Feel free to change the description of the setting.
Maybe say you shouldn't touch it if you don't know what you're doing
Fixes #17
