How much would you let an AI agent spend without asking? Prepaid caps emerge as favorite guardrail
alpharomeo777 · reddit · 2026-10-15
A Reddit discussion on how much money people let agents spend autonomously. The author stopped using a real credit card after an agent bought an ESP32-S3 from a sketchy site at 40% over price. His solution: a prepaid balance (e.g. a $50 gift card) as a hard loss cap — okay with $5-10 convenience premium, not with 20-30% overpayment or $25-30 extra. Thread debates per-day/per-agent limits vs. no payment rights at all.
