How to use Pro/Commercial version of IP-API

Hello, we noticed that the use of IP-API is only allowed for non-commercial use.
Since we don’t know if our site can be considered a “commercial” site, we wondered how we can possibly use the Pro version through API key.
Do you plan to include a setting screen in the future where we can set the key?

Alternatively, can you list in the README which types of sites can be considered for non-commercial use?
For example, our site is not an e-commerce site, but a multilingual site (7 total) where products are presented even if not sold. The purpose of having the IP detect is to redirect the user to the correct language version of the site.

We think there is some confusion on this aspect and it should be explained better.

Please note: due to company policy, I cannot link to the site in question.

Thank you in advance for your support.
