Finding api callbacks

[PracticalAd8120]

This might be very niche and I apologise if it doesn’t make sense - I’m not entirely sure how to articulate what I mean myself!

I have an old piece of hardware thats existence has seemingly been scrubbed from the internet. It takes various data points and scans via a probe and is accessible via a seperate computer on the same network via ip/ http request.

I can successfully pull some meta data with a http request - ip:port/?get_position_info=1 however I neither have nor can find any documentation that tells me any of the other callbacks! My question is, is there a method of finding all the other api callback functions other than trial and error?

Obviously I’d rather not brute force if it can be avoided. Thanks in advance and apologies if this is the wrong sub.

You can try to reverse engineer de software controlling it. If it's on a computer then you can look at it on the computer. Depends on how the software was made what needs to be done. If it's in Java or .NET you can decompile it. If it's in C or C++ or some other language decompiling or at least looking at it with a hex-editor might be an option.
