zeus is great for zapping and invoicing!

but for the vanity LNURL, there are different issues, atleast when I last used their zeuspay LN url service. basically youre zeus device has to be online non stop for it to work. They do have something that holds it for you temporarily, but yes very slow, or didnt work at all half the time. had to refresh multiple times or keep trying, and sometimes even that didnt yield results.
