Thanks for the feedback, I originally tried to import all domains ~1b, but that took a week, so I'll always be a week behind unless I do some serious optimisation there!
Currently using godaddy API, which has FAST or ACCURATE options. Given the generator requests are already 10s long (most of which is gpt4) I opted for the FAST, but I can trial it with the ACCURATE and see how it goes.
Thanks again!
