Chilkat wrapper highlights (off the top of my head)...
Wrappers are VCX classes. For a Chilkat method, there's a corresponding VFP method with a header containing some pertinent info, like a one line description, followed by the full online description for that method. If a method parameter accepts a 0/1 parameter, you can pass a VFP .F./.T. with a property setting on the object. If the method returns a 0/1, another property setting will return a .F./.T. for your convenience. The code for the method is very straightforward and plain to aid understanding. Lotsa side stuff handled in other methods.
Properties all have hidden access and assign methods. The access method will contain the online Chilkat description for that property. The access and assign methods (in essence) route the call to their Chilkat equivalent type methods - LongBit, LongBitReadOnly, String, StringReadOnly, etc. - but that's all beneath the sheets. This is done to save on coding...as it is I'm already up to 15 megs or so, probably 85% comments of one form or another.
Both properties and methods will do version testing if required -- methods will test within the method itself while the property version number will be passed as a parameter.
There's also object version testing where necessary. For instance, the Rest control came out in version 9.5.0.58. If you're on version 9.5.0.57, you don't have this class!
If you peruse the property sheet you'll see whatever description I could fit in the space.
Undocumented/decremented properties/methods/class(es) have all been added. Where I could find documentation I added it. It looks like there were methods and properties that returned or passed VFP DateTime values that are now not documented. I've pointed them out where I could.

It exists, you haven't seen it yet. I'm working on a VFP tool that wraps *everything* in the Chilkat library. Over halfway done. There's 103 classes (1 deprecated) and I've wrapped maybe 61 of them?
I too experienced *exactly* what you experienced re: Chilkat. The upside - They do document well. The downside? They document well. It's all on one web page per class and hard to see the big picture. To their defense, I don't necessarily have a better way to display such information on the web.
Rest is one of the classes I've wrapped, FWIW but that may not necessarily help clarify your issue. If you think it might, just send me an email - or I'll take a look at it.
If I complete the wrapping I may do something similar with their example code.

I have a spec project where I need to build an application using a REST API to extract data elements and then post those data elements to a different system. The API requires me to get a token upfront (which has a five-minute life span), issue my requests with the token and then get the results back in a JSON or XML format. Based on recommendations I received at the Virtual FoxFest earlier this year, I purchased the Chilkat tools and dove into what has turned out to be the deep end without knowing how to swim. The documentation at Chilkat while extensive is almost too extensive for me to understand exactly what I've got to do to make this work.
So far, I've been unable to even get a token back. All I seem to be able to get back from the server is
400 Bad request
Your browser sent an invalid request.
That response has been less than helpful. I've reached out to the API Provider but their answers are focused on requests issued after I get the token.
My question is this: Does anyone have any sample Foxpro code they use for a similar process (Request a token, then make requests with the token) using the Chilkat tools they would be willing to share? A Foxpro wrapper would be too much to hope for, but that would be even better if it is exists. I've got to get to a point where I'm beyond this initial stage to prove I can make this work.
Help! I know this is possible, but so far, I'm not making much headway.
