what os it on ?? linux.. would like to also go windows/raspberry pi and maybe macosx, as one machine = one root domain.,

It should work on any linux/unix, that includes raspberry pi and macos..
However you’d need to install jq..

Windows, erm, is a bit hassle to support..

I can later rewrite a php curl script, for godaddy(I can transparent to the OS systems). I did it before to auto make mysql databases godaddy/aws didn't network violations for this, since it was over 1000 x 2 gig dbs, on the farm. but I cheated, I stole the cookie from myself on the site, and automated some really long takeing dialogs. its nice how there is just a key and secret now. with all these oauth api coming out.

hack is to open dev tools(f10/12) in chrome, then 2nd click on the api http call and do 'copy as cURL' then paste that code,(fix it up a little), and a few variable, and add a loop and automate from database =]
