Hi! There is a company with an API to do this? I need to do a script where I can register and manage the domain without need to enter in the companies web site. Tks.
Well, you can contact registrars for this. But you'll need a cc or have funds in the registrar account...
You need to become a domain resellers at enom, etc. After that they provide you the API. You must have enough funds in your reseller account before you can register any domain using an API.
