American court prohibits Perplexity from using artificial intelligence for purchases on Amazon

The federal Justiça of the Estados Unidos ordered the startup Perplexity to immediately stop using its autonomous agent on one of the largest marketplaces in the world. The preliminary decision responds to an urgent request from the e-commerce giant to block automated access to restricted areas of its platform. The case is being processed in Tribunal Distrital of Norte of Califórnia and establishes a legal framework on data control in digital retail.

The center of the dispute involves a tool known as Comet, developed to carry out price research and finalize transactions independently. The court order suspends any activity of this system within password-protected accounts, even when the customer provides prior authorization for browsing. The restriction directly affects the software developer’s operating model.

The precautionary measure was issued at the beginning of the week and requires the destruction of all information collected by the virtual assistant during its period of operation on the website. The retailer argues that the practice violates federal cybersecurity legislation and exposes consumers’ sensitive financial information to unapproved external servers.

Grounds for the court decision

Judge Maxine Chesney, responsible for analyzing the precautionary request, considered that there is substantial evidence for a victory for the sales platform in the judgment on the merits. The judge highlighted that the permission granted by the consumer to the virtual assistant does not nullify the need for explicit consent from the company that hosts the digital infrastructure. Essa interpretation reinforces the power of corporations over the terms of service established for the use of their closed ecosystems and defines clear limits for the actions of robots in authenticated environments.

To guarantee the right to full defense, the immediate application of the order was suspended for a period of seven days, during which the developer of the autonomous system can present legal appeals. The startup has already signaled that it intends to challenge the injunction in higher courts, arguing that the restriction violates internet users’ freedom of choice when using new technologies. The legal dispute raises fundamental questions about the ownership of user accounts and the autonomy of individuals in managing their own access credentials.

Virtual assistant operating mechanics

The software targeted by the lawsuit operates integrated with a proprietary browser and works as an agentive artificial intelligence assistant. Essa category of technology goes beyond simple text generation, having computational capacity to perform complex sequential tasks in the online environment in an uninterrupted manner.

In practice, the system simulates the behavior of a human user browsing the website’s product and category pages. Ele can compare technical specifications, evaluate price variations between different sellers and add items to the shopping cart without any manual intervention from the account owner.

The final step of the process involves completing the payment using the financial credentials previously provided by the customer. Esse level of autonomy turned the tool into a popular option for consumers looking to optimize the time spent on internet market research and automate domestic supply routines.

However, the simulation of clicks and page scrolls makes it difficult for the platform’s security systems to immediately identify the source of traffic. Protection algorithms need to differentiate a real client from a highly sophisticated robot operating in the background, which requires constant updates to the anomaly detection infrastructure.

Security and law violation allegations

The sales platform’s legal department bases the accusation on federal law known as Computer Fraud and Abuse Act. North American legislation, originally created to combat invasions of government systems, punishes unauthorized access to computer networks and the improper extraction of protected data. The application of this law in cases involving artificial intelligence represents a legal adaptation to the new technological challenges of the digital market.

The company’s lawyers argue that the robot’s actions create critical vulnerabilities in the site’s security architecture. The exposure of order histories, home addresses and credit card numbers to third-party servers is identified as an unacceptable risk to user privacy. The retailer maintains that it does not have the technical means to audit how the startup stores or processes this confidential information after automated extraction.

The artificial intelligence developer refutes accusations of invasion and states that its operations occur with complete transparency and explicit consent from users. The defense maintains that the tool acts only as an extension of the consumer’s will, not constituting fraud or cyber attack. Para the startup, prohibiting the use of the assistant is equivalent to preventing a customer from hiring a human personal assistant to carry out their everyday purchases.

Damage to the retail business model

In addition to cybersecurity issues, the dispute reveals deep concerns about the economic viability of traditional marketplaces in the face of new technologies. Ferramentas completely ignore the advertising spaces and sponsored storefronts that generate billions in annual revenue for e-commerce platforms.

Blocking direct human browsing also negates the effectiveness of personalized recommendation algorithms developed over years. Sem the visualization of suggested products and cross offers on the device screen, the sales ecosystem loses the ability to induce impulse purchases, drastically altering the profitability dynamics of the retail sector.

History of corporate conflict

The judicial escalation represents the culmination of tensions that began to emerge in November of the previous year, when the first extrajudicial notifications were sent by the platform’s lawyers. The retail giant formally demanded that the startup cease operations of its shopping robot, setting strict deadlines for technical adaptation and data deletion. Diante After refusing to interrupt the service, the corporation opted to take the issue to court, transforming a commercial disagreement into a legal battle over the limits of artificial intelligence. The movement occurred in parallel with the platform’s own investments in proprietary automation solutions, such as virtual assistants Rufus and Buy For Me, created to keep the customer within the company’s controlled environment. Essa strategy demonstrates a clear attempt to monopolize virtual assistance in online sales, eliminating competition from external developers who try to mediate the relationship with the end consumer and capture part of the value generated in digital transactions.

Developments for the technology market

The litigation sets a precedent that will be closely monitored by the entire software development industry and Vale investors. Startups that create automation solutions will need to review their technical and legal approaches to avoid similar blocks on other large platforms that dominate the internet.

The future of automated transactions

The provisional decision guarantees the integrity of the retailer’s infrastructure while the main case progresses in the federal court of São Francisco. The final judgment will have the complex responsibility of balancing the right to technological innovation with the protection of private digital properties, determining whether a website’s terms of service have greater legal force than the direct authorization granted by an account owner.

Digital law experts estimate that the case will force the creation of new integration protocols between artificial intelligence companies and e-commerce platforms. The trend points to the requirement for specific commercial contracts and the mandatory use of official application programming interfaces to enable any type of transactional automation, ensuring that platforms maintain absolute control over data flow and advertising revenue.
