Charge fractions of a penny
per AI call.
No wallets. No credits. No prepaid tokens. Microz is the first payment API that lets you bill users $0.005 per interaction — and actually collect it.
No credit card required to start. 10,000 free test transactions.
// One API call. That's it.

Card fees eat sub-dollar transactions alive.
Every card swipe costs $0.30 + 2.9%. That means a $0.01 AI inference charge costs you $0.31 to process — a 3,000% loss. The industry's answer? Force users to buy credit packs upfront. That kills conversion.
The Solution
Accumulate first. Charge once.
Microz inverts the model. Users interact freely. Tiny charges accumulate invisibly in a micro-ledger. When the balance hits $5 or Day 6 arrives — whichever comes first — we collect with a single card charge. Users never see a wallet. You never lose to fees.
Built for the AI economy.
Every feature designed around the unique economics of per-request billing at sub-dollar price points.
How it works
User registers
User provides a card via Stripe.js. We tokenize it, verify with a $0.00 auth, and start the 6-day policy window.
Charges accumulate
Your app calls POST /v1/charge for each AI inference. $0.005 per call. No card network hit. Response in < 50ms.
Trigger fires
Balance hits $5? Or Day 6 arrives? Whichever first: we check the COGS floor, do a fresh auth, and capture.
Payouts route
Settlement collected. Each merchant gets their proportional share via Stripe Connect. Ledger resets. Cycle repeats.
Simple pricing
We make money when you make money. No monthly fees to start.
