Vanilla Js, Leaflet Api, Geo Ipify Api

works with any ip address also gives error message if it does not recognize users input works with domains without https for eg instead of https://youtube.com type youtube.com instead. I couldnt decide wether to make api call once the page was loaded or wait for a user to type something and click i decided to make a call when the page loads also does anyone know of a way to detect in your js if you are allowed to call an api for eg if using the geo ipify api you run out of your allocated number of requests how do you detect that?
