API or sees the cost of gasoline in the cities of the world?

Question

API

I write about road trips. For a motorist, of course, the price of gasoline in a particular country (city) is essential information. I would like to receive bottom data via API or a widget for cities (like the weather). I found only a paid option for 40 bucks a month, and they don’t even give a try.
There are other options?
