API JSON query

There are https://www.dellin.ru/requests/?requestType=truck-...
You need to implement the request and get the cost of JSON or html or another in return
they have an Api service but the calculation of the whole machines is not described
API description https://dev.dellin.ru/api/
Calculator number 1 https://dev.dellin.ru/api/calculation/calculator/
Calculator number 2 https://dev.dellin.ru/api/calculation/micro-calcul...

Not one of the calculator is not able to make a calculation of the delivery of an entire machine
(Dedicated transport -> transport by Eurofur)
https://www.dellin.ru/requests/?requestType=truck-...

Tech support says - its not leaned through the API
This site considers https://www.dellin.ru/requests/?requestType=truck-... without problems

The task of getting the same calculation :)

There is a key to the API

Cost and timing will be discussed
