[Disclaimer: I'm not using AI except Gemini in the main page of https://www.google.com/ and I'd never give a bot my credit card, even indirectly.]

If I wanted to use it, I'd like something like max $10 per day, and $100 per month, just to be sure I don't get a huge bill at the end of the month. Perhaps also a weekly cap. (I'm imagining a single person personal use. For a business or consultor it may be higher.)

To increase the amount, the site must ask for a blood sample, to ensure the bot can not fake it (for now).

I'm not in your probable client list, but I read too many horror stories like "a hacker stole my ASW credential and used it tu mine crytocoins". ASW many times drop the bill, but they are bigger than you.
