Sometimes they can complete a purchase without asking you to approve that individual transaction—but that does not mean an AI agent has unlimited authority to spend your money. Whether a purchase is within bounds depends on what you instructed, what the product flow asks you to confirm, and any limits set on the payment method or task. A payment tool’s technical ability to charge an account is not proof that you authorized a particular purchase.
What does “without your permission” mean?
Permission can mean several different things in a shopping flow: permission to search, permission to choose an item, permission to prepare checkout, or permission to pay. A request such as “find the best running shoes under $100” clearly asks an agent to research options; by itself, it may not make clear whether the agent should merely recommend shoes, prepare an order, or place one.
To judge a particular purchase, compare it with the scope you actually granted:
- Task: Did you ask the agent to buy, or only to find or compare products?
- Item and seller: Did you approve this product, merchant, or category?
- Amount: Does the total stay within your limit, including any shipping or other charges shown before purchase?
- Timing: Did your permission apply to this purchase now, or was it limited to a set period or task?
- Confirmation: Does the flow require you to approve the final order, or can it spend within a budget you set?
Stripe’s service terms use “Authority” for the express scope a customer grants an agent in Stripe’s defined service setting, including applicable spending limits, merchant restrictions, or time limits. That is contractual language for that service, not a universal legal definition. The practical point is that an agent can be technically capable of making a transaction while the transaction still falls outside the permission given to it.

Which purchase flows require approval?
AI shopping systems can put the approval boundary in different places. The following are product designs described by OpenAI, Stripe, and Visa; they are not guarantees that every merchant or implementation works the same way.
| Flow | What the described system does | What to check |
|---|---|---|
| Confirmed checkout | OpenAI says that in its described Instant Checkout flow, the user taps “Buy” and confirms the order, shipping, and payment details. | Read the final screen: check the item, seller, total, delivery details, and what the confirmation authorizes. |
| Delegated payment token | OpenAI’s developer documentation describes a one-time payment request with a maximum charge and an expiry. A trusted payment service provider creates the token used by the merchant. | Check the maximum amount, expiry, seller scope, and who can redeem the token. Tokenization limits credential exposure; it does not answer every question about authorization or disputes. |
| Wallet or task budget | Stripe describes buyers funding a wallet and setting spending limits. Larger purchases may require individual approval or a task-specific budget. | Check the budget, duration, merchant or category restrictions, and what happens when the agent cannot complete the task within those limits. |
| Programmatic machine payment | Stripe describes usage-based payments, such as per-request or per-session purchases, that can occur without a person approving every transaction. | Look for clear pricing, a maximum spend for the task, transaction records, and a way to stop further charges. |
Visa says its AI-Ready Cards approach uses payment credentials tokenized for specific agents and use cases, alongside real-time authorization and fraud monitoring. Visa describes possible user controls such as spending limits, merchant-category restrictions, and approval requirements. Those are stated capabilities of Visa’s approach; how they work depends on the implementation.

What can you do before letting an agent spend?
Set the boundary in the product or payment flow rather than relying on a broad instruction when you mean something narrower. For example, distinguish “show me options under $100” from “buy one pair from this seller for no more than $100, including shipping, after I confirm.” If a system offers a budget or payment token, check its scope and expiry before enabling it.
- Use an individual confirmation requirement if you want to review every order.
- If you permit spending without transaction-by-transaction approval, set a budget and, where available, restrict the merchant or category and limit how long the permission lasts.
- Review what the agent will share with the seller and which payment details it can use.
- Check where the transaction history appears and how to pause or revoke the agent’s payment access.
- Keep the order confirmation and transaction record so you can identify the seller and payment provider if something goes wrong.
These controls can reduce the chance or impact of an out-of-scope charge, but they do not guarantee that an agent will interpret instructions correctly or that a payment will be easy to reverse.
Who handles an order or a disputed charge?
In OpenAI’s described Instant Checkout arrangement, the merchant accepts or declines the order, processes payment through its provider, and handles fulfillment, returns, and customer support. OpenAI says it passes necessary information between the user and merchant and is not the merchant of record. Stripe’s terms likewise assign sellers responsibility for fulfillment and post-fulfillment matters such as shipping, returns, refunds, and exchanges in the service setting covered by those terms.
If an order is wrong or a charge is disputed, identify the seller and the payment provider shown in the order or payment record, then contact the relevant party. Also check the platform and payment terms for that specific transaction. Stripe’s terms allocate certain unauthorized-transaction risks between Stripe and its user; that contractual allocation should not be assumed to decide a customer’s rights against a seller, card issuer, or other party.

Does the law let an AI agent buy without approval?
The product descriptions and service terms above do not establish one legal rule for every AI purchase. Whether a transaction was authorized, who may be responsible, and what remedies are available can depend on the transaction facts, the applicable contracts and payment arrangements, and the jurisdiction. A product’s ability to make a payment—or a company’s description of its controls—does not by itself resolve those legal questions.
