API for flight details

Hello everyone, it's my first time posting in this sub. Hope everyone is doing good. Before anyone blasts me by saying just google first, I just want to say that I did, but I couldn't find what I specifically wanted or needed (even though I assume I thought I would) Basically what I want is an API which can tell me the model of the flight using the flight details I recieve after booking, (eg. via PNR number, etc etc). Is this possible? Are there any public APIs for this? Thank You!!
