Truckinator

I tried to post this topic in https://forum.truckersmp.com/index.php?/forum/198-developer-portal/ but it says I do not have access to post there ? I am working on a VTC and need to know if there is a JSON file or API that can help me get the list of companies available in each city? It is basically what the Truck Delivery Dispatcher has but not sure if this is available as a list. I want to be able to select a city on my website and get all the companies available in that city. Does anyone know if there is an API or publicly available list for this that is available?
