A wallet for each agent
its balance is the worst case
An agent pays for data and services by x402 from a wallet whose balance is its whole budget. Every payment has a receipt: which agent, whose money, to whom and who decided.

The tiles are the fence: what the wallet holds, its day and its ceiling per request. Below, what it paid, the host that asked for a new address and the transfer that waits for you.
How it works
Agent wallets
in four lines
- The balance is the budget
- You fund the wallet, and it can never spend more than it holds. What is left comes back out whenever you ask, with your second factor.
- Two ceilings and a list
- A ceiling per request, a ceiling per day and the hosts it may pay. A purchase past either is refused on the spot, and an empty list pays nobody. A transfer past the day waits in your queue.
- An address pinned
- The first payment to a host pins where it was paid. A host that asks for another address is refused until an owner confirms it against the host's own documentation.
- A card is its own fence
- An agent can hold a card as well. The balance loaded on it is its whole limit, and freezing the agent stops the card too.
Questions
Agent wallets
the short answers
What is the worst case if an agent goes wrong?
What its wallet and its card hold. It cannot pay from your accounts, where anything it wants is only a proposal, and a host cannot quietly change where it is paid.
How do I choose what it may buy?
Find a service searches catalogues of x402 sellers by what they do. One press of Allow opens that host to the agent and files it as a supplier, with an optional monthly cap.
