why agent payments won't use credit cards

agents paying agents autonomously, at transaction sizes where card fees make the math impossible — that's the future of agentic commerce.

if an agent calls 500 APIs in an hour and each call costs $0.003, credit cards don't work. the $0.30 + 2.9% fee structure wasn't designed for microtransactions. stablecoins and pay-per-call rails are the only option that pencils.

this creates two problems for developers shipping agent tools today:

1. your billing system assumes humans with cards
2. your compliance stack assumes KYC'd individuals, not autonomous processes

mnemopay solves the second part. it treats each agent as a spending identity with a parent account, hard caps, and an audit log. you don't need to KYC the agent — you KYC the human who deployed it.

the standards are still forming. 8 different consortiums launched agent payment specs in the last 90 days. none of them are compatible. that's fine — the teams building now will shape what wins.

if you're waiting for consensus, you'll ship in 2028. if you're okay with adapting as the category settles, you can own a niche today.

the wedge is simple: let agents spend small amounts autonomously, log everything, and make it easy for the parent account to pull the plug. everything else is just API design.
