it's a nice idea!

but yes there is very sparse information and instead of examples i get "NetworkError when attempting to fetch resource." and it says "free" here and there but free forever, free until?

Ah, sorry about the error! I guess it could use some optimisation. It will remain free for the users. I haven't thought about monetisation but for sure it won't be on the final user. Either ads or sponsored places by companies etc. Similar to TripAdvisor
