Is it practical or even possible to generate a REST API for the LCL
controls?

Can it be generated automatically from its published properties?

I just saw this announcement New Swagger/OpenAPI Client Generator for
FPC  by @abouchez.

Forgive me if my question sounds stupid, but REST APIs have never been
a thing for me. I've never truly worked with them.

I don't know if I understand your question correctly but check the
following package
lazarus->components->sqldbrest-> lazsqldbrest.lpk
It is a package to assist you visually in creating REST endpoints
direct from data.

Yes, that is possible.
A good example are the Google API' s that are machine generated and
fully rest.
The package also contains the code that does the actual generation.
You could adapt it to an LCL api generator since components can
already be represented in JSON,

Hello,
here is an example using SQLDBRestBridge
In attachment a zip file with two projects and a sqlite3 database
to compile the projects you must install  lazsqldbrest and weblaz
packages. To use the sqlite3 database you must have the sqlite client
library installed.
The first project restreadonly launch a rest api server on port 3000.
This server is connected to the sqlite3 database .  The connection to
the database is here in the code :
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i begin    //
Or set in code.   // C.ConnectionType:=TPQConnectionDef.TypeName;   //
C.DatabaseName:='fpctest';   // C.HostName:='localhost';   //
C.UserName:='user';   // C.Password:='secret'; 
 C.ConnectionType:=TSQLite3ConnectionDef.TypeName; 
 C.DatabaseName:='selzig.db3';   // C.HostName:='localhost';   //
C.UserName:='user';   // C.Password:='secret';    end;The second
project jsonclient  is used  to connect to  the rest Api server and
get data in json format.
the two projects come from fpcsource and lazarus.
