Using Compare Document tool of Adobe pro via IAC or OLE or Web-service

Hi,

I am developing VBA code where I can use/Call the compare document tool provided by adobe in the DC pro version . How can I do that. Is creating a custom action a better choice. Also, I read in adobe forums that Compare tool is not available as an API. Automate Compare Files

Is it available in the latest version now.?

Also, Is there a web service that I can use of Adobe that will let me do the PDF compare.

Thanks
