IP Address Tracker w/ vercel's serverless function

I used vercel's serverless function backend stuff here for the first time. Decided to try free ip-api.com to avoid all the api-keys hassle, but it lead to two problems:

1. My adblocker blocked access to ip-api.com
2. After the first deploy to vercel I found out that it's forbidden to fetch via http when you are on the encrypted https site.

I thought that a bit of backend should solve both problems and it did.

Apparently there is no native fetch in node.js so I thought it's a good moment to try axios. This solution uses both, axios on the backend and fetch on the front.

At first I tried using Leaflet.js but it looked very blurry with my 125% scaled ui. I went with Yandex maps as the easiest option with no api-keys needed.

Also made a couple of custom hooks for the first time!

I'd appreciate any feedback on my api or react code.
