your AI agent

starts with a prompt

“Get me sushi for under $400, from the usual place.”

1
Prompt your agent. Groceries, flights, API credits, anything with a checkout.
2
It mints a card for the job, capped at the budget, locked to the merchant type, single-use if you like.
3
It pays. The charge clears five checks in milliseconds. Anything over your limit pings you first.
4
Dinner shows up. The card is already gone.

under the hood

Overspending isn't blocked. It's impossible.

Every unit of value lives in a double-entry ledger, counted in whole cents. A charge that would exceed the balance simply can't be recorded. The accounting refuses it.

Card numbers never touch our servers. Every charge clears five checks (signature, exactly-once, rules, your approval, ledger hold) in milliseconds. And the whole thing is open source.

Your card stays in your pocket. Theirs self-destructs.

disposable cards

One charge, then gone

Cards can self-destruct after a single use. Your agent never holds anything worth stealing.

Approvals, on by default

Hey :) your agent wants to spend $842.00 at a merchant. Authorize?

setting up

Four steps, about five minutes.

No developer needed. If you can add a card to an online shop, you can do this.

1

Make your wallet

Sign up with your email. That's your wallet, the place your agent's money lives.

2

Put money in

Add $20 to start, or connect a card you already have. Your agent can never spend more than what is in there.

3

Set your rules

Pick a spending cap and the amount above which we should ask you first. Two numbers, that's it.

4

Connect your agent

Paste one line into Claude Desktop, or use our chat. Now just ask it to buy something.

Not technical? Skip step 4 and use our chat instead. Everything works from your browser.

for enterprises

A fleet of agents. One set of controls.

Give every agent in your organisation its own card, its own budget, its own merchant scope, and route every approval to the right person, not a shared inbox.

Finance sees one ledger. Security sees every decision. Nobody shares a card number, because there are no card numbers to share.
