Case No.: 3:25-cv-09514-MMC details a legal clash that moves beyond licensing disputes into federal regulatory enforcement. As Amazon.com Services LLC filed a first amended complaint against Perplexity AI, Inc. in the United States District Court Northern District of California San Francisco Division, the filing outlined a direct confrontation over automated access to protected digital systems.
Amazon operates the Amazon Store, an online platform serving hundreds of millions of customers. To manage this operational scale, the platform relies on controlled user interactions and authenticated accounts. Perplexity operates AI-based products and services, including an application called Comet that features agentic AI functionality.
This case is not about stifling innovation; it is about unauthorized access and trespass.
Perplexity built an AI agent to operate inside the Amazon Store in ways that Amazon’s Conditions of Use forbid. The Comet application allows users to browse the internet and to ask the Comet AI agent to carry out tasks, including making purchases. The Comet AI agent operates through Perplexity's servers and remains under Perplexity's direct control and execution.
The Architecture of Autonomous Infiltration
Amazon alleges that Perplexity disguised an automated agentic browser as a human user to evade Amazon's technological barriers and access private customer accounts without permission. By mimicking standard user sessions, the autonomous software bypasses traditional perimeter defenses designed for human visitors.
This behavior creates an asymmetrical load on corporate infrastructure. Automated agents execute multi-step workflows without generating the ad revenue or customer loyalty loops that traditional web traffic depends on. How long can digital platforms absorb this unmonetized computational overhead before locking down access entirely?
The legal filing asserts that Perplexity bypassed technological roadblocks repeatedly. Amazon brings this action to stop and remedy Perplexity's ongoing tortious interference with the contractual relations between Amazon and its customers.
The Shift Toward Infrastructure Restructuring
As autonomous agents scale their interactions with commercial websites, companies face mounting pressure to deploy aggressive defensive measures. Protecting private customer data requires heavy investments in cybersecurity infrastructure and constant updates to block unauthorized agentic scrapers and shoppers.
Perplexity gained persistent, covert, and unauthorized access into Amazon's protected computer systems in violation of federal and California computer fraud and abuse statutes. When software agents masquerade as real buyers to navigate password-protected areas, platforms respond by tightening authentication and restricting automated pathways.
They promised an open web navigated by intelligent digital assistants. They delivered a landscape of locked APIs, escalating litigation, and automated border controls designed to keep software agents out. They called it the future of digital commerce.
