index thousands of websites?

Hi,

i want to index handreds of new website, blogs, on a daily base.

using GSC is the last option, as i couldn't find a way to do this other than one by one.

no need for ******** backlinks, just make google (and others) start crawling these website.

is there a way or tool for that?is there a way or tool which can cause GG and pindex these websites in an automatic way.

thanks
