I doesn’t have an anonymous top up with bitcoin way to use, but it could. If what they need it for it to be able to limit the searches according to the plan you get, Kagi could go the MapleAi route and offer all options :)

What do you think , nostr:nprofile1qy2hwumn8ghj7erfw36x7tnsw43z7un9d3shjqpqxsgymm0ne3vndqpvsvy285qfpu59049t5n5twg9vetmt92cyn95s85lzva ?

Any chance for anonymous searching?
