Hosting detection is a finite process, meaning that there is a finite amount of hosting providers out there to detect after all. Challenge lies in staying up to date.
So maybe we can make a compromise and state that ipinfo.io is likely a bit better than ipapi.is in hosting detection.
But ipapi.is for sure detects some hosting provider's that you don't. Examples:
https://api.ipapi.is/?q=185.45.13.144
https://api.ipapi.is/?q=185.50.248.0
https://api.ipapi.is/?q=91.102.88.0
Summary: Your product is maybe a bit better in regards to hosting detection than https://ipapi.is/, but it is much much much much more expensive ;)
A great IP intelligence solution is also ipregistry.co
https://ipapi.is/ is not as good in regards to geolocation, but our hosting detection is more advanced and https://ipapi.is/ is much cheaper...
Running an opensource AI model to perform translation may help and work in some cases but to be honest this has also a lot of limitations. The first being processing time and the second languages support. I am not even considering accuracy.
