Your agent shops. You approve. Your card stays yours.
Connect the card you already have, hand any agent a Marutap token, and tap to
approve. It pays with a single-use card scoped to that exact purchase — your real card is
never exposed.
On it. Large pepperoni from Gino's Pizza — $24.50 with delivery.
You've got Marutap connected, so it's one tap:
◯Confirm $24.50 · Gino's Pizzamarutap.com/approve · single-use card, this purchase only
✓ You approved on your phone
Paid. Order confirmed — ETA 35 minutes. I never saw your real card.
How it works
1
Connect once
Sign up, connect the card you already have, and drop a Marutap token into whatever agent you run.
2
Your agent requests
When it wants to buy something, it asks Marutap instead of holding your card.
3
You approve
A receipt hits your phone. Tap once — Marutap hands the agent a single-use card locked to that exact purchase.
Why Marutap
The only approve-first payment layer you can adopt with nothing but the card
already in your pocket — no new credit line, no new wallet, no
subscription — and the only one where your rules, subscriptions, and ledger span every
agent you run.
◯Never give an agent your card. It gets a single-use card scoped to the amount and merchant you approved.
◯You approve every purchase — until you set rules to auto-approve the small, routine stuff.
◯Works with any agent. Claude, or any MCP-capable runtime — Marutap is yours, not tied to one app.
◯Prompt-injection safe. A hijacked agent can't quietly overspend — nothing is paid until you tap, and what it gets is a single-use card scoped to exactly what you approved.
◯It adds up. One ledger, one set of rules, one kill switch — across every agent you run.
Subscriptions you can actually cancel
Let your agent set up recurring payments — Netflix, your gym, whatever — as a
locked mandate, never a card on file. You approve the cap once.
◯Cancel and they're done. Kill it from your dashboard and the merchant can never charge you again — no dark-pattern cancel flow can stop you.
◯Price hikes get declined. Bump the price above your cap and the charge bounces — until you approve the new one.
◯Locked to one merchant. Capped per month and usable nowhere else — a breach there can't touch the rest of your money.
Pricing
◯Free. The approval loop, single-use cards, subscriptions, and notifications — the whole core product — cost nothing.
◯Pro — coming soon. A richer spend dashboard and automation controls (auto-approve rules, category limits). Priced in-app before you ever pay; cancel anytime.
