TechSmith products (Snagit, Camtasia) offer automation through the Snagit COM Server API (Windows) and Camtasia's command-line batch processing. No traditional API keys -- COM registration is the auth mechanism.

print(f"Snagit version: Connected via COM")
using SNAGITLib;
var capture = new ImageCaptureClass();
Console.WriteLine("Snagit COM initialized");
