OpenCAGE | modding toolkit for Alien : Isolation that gives access | Game Engine library

I have read and attempted to implement all solutions I found on the web but until now I can't get this to work, so time to ask for help:

I am reading API Policies and have some questions.

We are working on a social networking app and need to access user location. Whenever users publish a post, system will show users location on the NewsFeed, our system will not store the complete data, but only City and district.

we are surveying here-api,opencage and Mapbox.

for here solution, I found a discussion on similar use case, and it seems to be answer by here suppose engineer, just wondering if we could implement the same method?

Here API states that I cannot store results. So how can I use it for address validation/completion?

My function returns me data as shown below. How can I get specific information from this data, for example country?

Is it possible to get a route like between origin and destination using the opencage API like the way GoogleMaps provides a route using origin and destination
