Wait.. Using this can we make new VISA accounts? and eventually create a VISA debit card for Bitcoin sort of thing for ourselves?
nooooooooope!!!!! LOL

Or is here any easy way to get API calls to funding VISA accounts
Exactly!
What i did for my company was to use my xapo card (which is ALREADY VISA and issued by mychoicecorporate) as the central wallet to fund all other (not bitcoins) VISA cards using their API calls.
