Delivery of transport companies in Russia php?

Question

API

Is there somewhere a common api for the delivery of these transport companies, so as not to make a request to each separately?
I just need to calculate the cost to the city according to the minimum parameters, that is, to receive information
so that it is, for example, like on this site

"Почта России»
«ПЭК» 
«Деловые линии»
«КИТ - транспортная компания»
«ЖелДор экспедиция»
«Байкал-Сервис» 
«EMS»
«Ратэк»
«Энергия»

Answer 1

It is not clear what exactly you need from the TC. Some of these companies require a contract even for tracking.
There are plenty of tracking aggregators, but they use either open API sections or various hacks.
There are no dispatch aggregators and cannot be.
Calculation aggregators are googled for a simple query , for example, this one .
