Form autocomplete in nova

Hi! i need to pre fill a form in nova with data coming from a webservice. Basically, the user need to insert a key field, then click on an autocomplete button which fill the rest of the form data based on the data retrieved from a webservice based on the key field. I'm already doing it in my other laravel applications, so all the underlying concepts are clear, but i'm wondering if there is some way to implement using nova without writing custom tools or fields.

Any ideas?
