need bulk domain search

I have scraped a lot of domains and I am checking them for PBN purposes.

I need a bulk domain searcher that has these features:
1) It should take full domains with extension included. for example, I want to check the availability of henry.org but not henry.com and henry.info and henry.us
2) export available domains - lets say I search 1000 domains and 200 are available. I want to be able to export the available ones as a list.

I have found domain registrars that have the first option, but the second option I have not found anywhere. any ideas?

Scrapebox has two plugins for this purpose .

check namesilo - it definitely has first not sure on the second option though.

I too suggest scrapebox.. It will help you a lot

scrapebox or have a botcoder make you a simple bot.

which add on? I dont see such add on in SB.
