How to check if delivery to the address is possible?

Question

JavaScript

The store delivers goods within a radius of three kilometers around itself.
It is necessary that when placing an order, after the user enters the address, a check is made to see if the delivery is made to the entered address.
Tell me plz, in which direction to dig?
Maybe there is a plugin?

Answer 1

There is a link to the code in the description.
Well, you can easily write the check itself from the received data.
