How to calculate the mileage for a courier between two points by coordinates?

Question

ORM

Hello.
We have a food delivery company, we want to pay couriers for mileage. But the company is not large enough to afford a matrix of distances, for example, from Yandex for 120,000 rubles a year.
How else can you calculate the distance between two points if the coordinates are already known?
It is necessary to lay the shortest path along the roads without traffic jams

Answer 1

If you do not need to solve the transport problem with path optimization, the usual Google maps
Distance Matrix API will suffice
