Is there any way to know the price per train section?

Please let me know if there is a way to know the price by section or API developed.

No way, I'm sorry.. It would be very hard to do, even if you had the tarif data - there are so many different cases and special tickets. The developers of Fairtiq (www.fairtiq.ch) and Lezzgo (https://www.lezzgo.ch/) know probably most about this topic as their business is to find the cheapest price for a particular journey.
