Pay as you go for stealer lists queries
I only have the one domain and its for my families email we use it because its easier to change ISPs and email services when needed. I recently got a notification, and I am really careful, so wondering what credentials for which services they have. However, I cannot afford the API price to query the stealers list. I wonder if there could be a pay as you go feature?

We already have this by virtue of monthly payments. But in your case, you can probably just use the free individual email address search. See the end of this blog post for steps: https://www.troyhunt.com/processing-23-billion-rows-of-alien-txtbase-stealer-logs/
