The connection between two APIs (Russian language)!

I have a vehicle transportation app(ride-hailing) similar to Uber or Bolt.
I am looking for a freelancer who adds a special API key for maps such as Google Maps, but from another site (https://nextbillion.ai/) to the server I work with, which is the motherboard for my transfer program! i want to use directions, places, and geocoding from nextbillion

These are the words of the company licensing my program:

You will not add functionality to TM directly.

You should set up an API for you on the side to communicate with TM.

I can't tell you how and what exactly and how a specialist will do it, because the developers deal with this issue, we don't prepare third-party API functions.

Yesterday I explained that the Open API functionality is sufficient to implement such a setup.

This is their confirmation:

An open API has already been implemented in TM.

Yes, a specialist will set up a connection between two APIs (in your case, between the site and TM).
