Give your agents a budget, not your card.
They pay for what they need: a few cents for a one-off, or a subscription you approved. Always inside the limit you set.
This property has a full ownership history report behind a paywall. It costs$0.40and is within your limit. I'll buy it and read it now.
The problem
Your agent finds it, then stops.
It hits a paywall. The work ends there.
Or you create an account and enter a card, for something you need once.
The wrong shape of payment for what you actually needed.
The agent did the hard part. The checkout is what broke it.
I found it, but it's behind a paywall. You'll need to create an account and add a card to continue.

Who decides what
The agent never holds the authority.
- Your agentsNotice a paid resource would help, and ask.
- PrioChecks it against your limit, your approval, and what it's for.

- The payment layerIssues a one-time proof, bounded to that purchase.
- The serviceVerifies and returns what was bought.
The agent decides what would help. You decide what's allowed.
You stay in control
Every payment happens inside limits you set.
One real task
A property-history report costs 40 cents.
The agent buys it, reads it, and the flat is on your shortlist before you wake up. No account to create, no card to hand over, no limit you didn't set.
Prio uses x402, the payment flow AWS and OpenAI are building on. It's the web's "payment required" response finally being used, so software can pay for one thing without creating an account first.

FAQ
What can my agent actually buy?
Things it needs to finish what you asked: a report, a dataset, a paid API call. Small, one-off purchases that would otherwise stop it dead. Not shopping.
Can it spend my money without asking?
Only up to the limit you set, and only on the kinds of things you allowed. Anything above that waits for you. You can pause or revoke at any point.
How much are we talking about?
Usually cents. You pay for what fits: a few cents for a one-off, a subscription when something gets used every week.
Where is the money kept?
In a wallet on your machine, under a limit you control. Not in an account we hold, and the agent never has direct access to the keys.
Do I need to know anything about crypto?
No. You set a limit and top it up. Everything else happens underneath.
