You tell an AI agent to buy printer ink. It logs into your Amazon account, compares options and gets ready to place the order.
Who just accessed Amazon: you, or the software acting for you? A US appeals court has now answered that question in Perplexity’s favor for one important legal claim. On August 4, the 9th US Circuit Court of Appeals overturned a temporary order that had barred Perplexity from using its agentic shopping tools on Amazon.
A US appeals court has given AI agents more room to act for users, but it did not create a universal right to access every platform.
UAE consumers using browser agents, AI shopping tools, saved logins or delegated purchasing features.
Agents can reduce search and checkout friction when the user clearly authorizes the task and the platform flow works.
The ruling addresses one US computer-access claim at a preliminary stage; platform terms, payment mistakes and account security remain separate issues.
The underlying Amazon case continues, while more platforms will need to define what user-authorized AI agents may do.
Use agent purchasing only with clear limits, review the final cart and keep high-value transactions behind a human approval step.
That is a significant signal for agentic commerce. It is not a permission slip for every AI agent to ignore every website rule.
What the Court Actually Changed
Amazon sued Perplexity over its Comet browser and associated AI agent, arguing that the software covertly accessed private customer accounts and violated the US Computer Fraud and Abuse Act, among other claims. A federal judge temporarily sided with Amazon in March and blocked the relevant agentic access while the case continued.
The appeals court reversed that temporary restriction. Reuters reported that the panel found Amazon unlikely to succeed on its CFAA theory because the users, acting through Perplexity’s agents, were the ones accessing Amazon under that statute.
The procedural words matter. This was an appeal about a preliminary injunction. The underlying lawsuit is not over. Amazon said it disagrees with the decision and is evaluating next steps. Perplexity said users should be able to choose the AI they want.
This Is Not a Global Right for Bots to Enter
The decision comes from a US federal appeals court and interprets a US computer-access law. It does not decide UAE law. It also does not erase contracts, platform terms, fraud rules, payment authorization, intellectual-property questions or other legal theories that could arise when agents act across websites.
So a UAE user should not read the headline as: my AI can now enter any account or website on my behalf. The safer reading is narrower: at least one important US court is treating user-authorized agent access differently from a third party simply breaking into a computer system.
That distinction will matter more as agents move from answering questions to actually taking actions. Our AI Agents Keep Crossing the Fence analysis focused on the security side. This case adds the platform side: even when the user wants the action, the website may have its own rules about how automated access happens.
The UAE Consumer Risk Starts After Authorization
Permission is not the end of the story. Once you authorize an agent to shop, what can it see? Can it open saved addresses? Can it use a stored card? Can it apply a subscription? Can it choose a third-party seller? Can it accept a non-refundable purchase?
Those questions are practical because agents compress several clicks into one instruction. The convenience is real, but so is the possibility of skipping the moment where a human normally notices the wrong quantity, delivery date, seller or return condition.
Our existing Perplexity AI review treats the product as useful for research with citations. Agentic shopping is a different risk class because the system is no longer just giving information. It can touch an account and potentially create a transaction.
A Good Agent Needs a Spending Boundary
The simplest consumer rule is to separate research from irreversible action. Let the agent search broadly. Keep purchasing authority narrower.
For low-value repeat purchases, a user may eventually be comfortable with an approved merchant list and a small spending cap. For electronics, travel, subscriptions or anything with complicated returns, the final checkout should still show the item, seller, total price, delivery commitment and cancellation terms before money moves.
Saved credentials deserve the same caution. A browser agent that can log in for you is handling something close to a key. Do not give that capability to a random extension or an unofficial copy of a popular agent. Use official software, strong account security and separate approval for sensitive actions.
Businesses Have a Different Problem
For merchants, this ruling is another sign that machine customers are becoming part of normal commerce. We recently explained why your customer may ask ChatGPT before they see your store. The next step is agents that do more than recommend. They may compare, sign in, reserve and purchase.
That means a business needs to distinguish useful agent traffic from scraping or abuse. Product information should be clear enough for machines to understand, but checkout systems still need authentication, rate limits, fraud controls and a way to know when an automated action is actually authorized by the customer.
The future is unlikely to be websites choosing between humans and bots. It will be websites deciding which bots may act for which humans, under which permissions.
The Robius Read
Amazon versus Perplexity is not just a fight between two technology companies. It is an early argument over who controls the user’s delegation rights on the web.
Users will increasingly say: I gave this agent permission to act for me. Platforms will increasingly answer: that does not mean your software can interact with us however it wants.
Both positions can be true at the same time. The winning agentic-commerce model will need user control, platform-compatible access and transaction safeguards. A court ruling can move one boundary. It cannot remove the need for the other two.
