Amazon vs. Perplexity – U.S. Court of Appeals for the Ninth Circuit

📝 Discussion Summary (Click to expand)

Four prevalent themes in the Hacker News discussion

1. Legal interpretation – whether the AI assistant’s actions constitute “unauthorized access” under CFAA/CDAFA

Many commenters stressed that the Ninth Circuit overturned the preliminary injunction because the court found the user, not Perplexity, performed the access.

“The Ninth Circuit held that Amazon was unlikely to succeed on the merits of its claims because Perplexity did not ‘access’ Amazon’s computers within the meaning of the CFAA or CDAFA; instead, the access was performed by the user employing the Assistant as a tool.” – swyx

“They haven’t ‘won’ yet … the injunctions and appeals are very important, but they are details of the suit proceedings, not the case itself.” – willy_k

“The case hasn't actually been to trial on the merits yet and is still undecided.” – Legend2440

2. Business motive – Amazon’s attempt to protect its advertising revenue and control of agentic commerce

Several users argued that Amazon’s lawsuit is driven by fear that headless, agent‑mediated shopping undermines its lucrative ad business.

“From a business perspective AI is a legit threat to Amazon because headless Amazon makes it more difficult for Amazon to sell ads, which is a large part of their revenue.” – gz5

“Amazon wants to control ‘agentic commerce’ use cases so they can monetize them. A generic agent using amazon.com undermines that effort, so they're trying to use the courts to prevent it.” – hamdingers

“If other tools or agents take that over, Amazon is left holding the bag on a very useful but ultimately boring logistics business that makes no money.” – cmiles8

3. Technical agency – the AI tool is merely an extension of the user, comparable to a browser or a hired helper

Analogies to browsers, secretaries, or ad‑blockers were common, emphasizing that the user remains the actor.

“What Perplexity does, from my perspective, is essentially the same as when I allow Firefox, Chrome, or Safari … to see my credentials and access Amazon's website on my behalf.” – eigencoder

“An ‘agentic workflow’ does the same thing. It's a computer program that I run that makes requests to the site, chooses how to display the content provided, and then gives me control mechanisms … to interact with the content.” – eigencoder

“Maybe a better analogy: They can ban you from going through their drive through on a bicycle, but can they sue bicycle manufacturers because bike riders are going through their drive through?” – A1kmm

4. Open‑source / decentralized alternatives – building agent‑first marketplaces to bypass Amazon

A contingent of commenters advocated for open‑source, LLM‑powered commerce platforms that let users shop directly from sellers.

“I’m building an open-source, decentralized Amazon alternative that’s powered by agentic commerce and MCP‑UI that brings the cart and storefront into the chat directly.” – theturtletalks

“With LLMs, you can go directly to the website and checkout instead of going thru Amazon so they can collect their commission.” – theturtletalks

“It’s why I’m building an open-source, decentralized, interoperable marketplace. It’s powered by agentic commerce and we include a list of vetted stores but you can bring your own.” – theturtletalks

“Nice, have a github repo? This is something I've thought about trying to build, seems like the future.” – ericd

🚀 Project Ideas

Agentic Consent Proxy

Summary

  • Provides a local, user‑controlled proxy that lets AI agents perform browser actions (clicks, form fills, navigation) on behalf of the user while keeping credentials, screenshots, and DOM data on the user’s machine.
  • Core value: Enables agentic web interactions that comply with site ToS and reduce CFAA risk by moving execution client‑side and providing signed consent tokens to target sites.

Details

Key Value
Target Audience Privacy‑conscious power users, AI agent developers, early adopters of agentic commerce
Core Feature Local execution engine (Playwright/Puppeteer) + consent token generator; integrates with any LLM‑agent framework via a simple REST/WebSocket API
Tech Stack Electron/Tauri desktop client, TypeScript, Playwright, Web Crypto API for signing, optional Rust backend
Difficulty Medium
Monetization Hobby

Notes

  • HN commenters expressed discomfort with agents sending screenshots to Perplexity’s servers (“sending browser screenshots to Perplexity’s servers for further instruction”) and wanted agents to act on user‑provided credentials without being treated as hacking.
  • Enables open agentic commerce while addressing legal concerns raised in the Amazon vs. Perplexity case, potentially reducing injunctions and litigation.

Open Agentic Commerce Marketplace SDK

Summary

  • Open‑source library and adapters that let any e‑commerce store (Shopify, WooCommerce, Magento, custom) expose a standardized agent‑friendly API (product catalog, cart, checkout) using MCP‑UI or GraphQL.
  • Core value: Enables a decentralized, interoperable marketplace where AI agents can shop across stores without being locked into a single platform, lowering fees and avoiding platform‑specific dark patterns.

Details

Key Value
Target Audience Small‑to‑medium merchants, indie developers, agentic AI product builders
Core Feature Adapter plugins that translate store’s native API into a common Agent Commerce Interface (ACI); includes UI components for chat‑based storefront
Tech Stack Node.js/TypeScript, OpenAPI spec, Docker, optional WASM for sandboxed adapters; can be self‑hosted or deployed via Vercel
Difficulty Medium
Monetization Revenue-ready: Subscription $20/mo per store (or 0.2% transaction fee on processed orders)

Notes

  • Commenters like @theturtletalks advocated for an open‑source, decentralized Amazon alternative (“You can use our vetted stores but add your own”) and wanted to route orders directly to sellers.
  • Provides the technical foundation for such a marketplace, addressing the desire to bypass Amazon’s ad‑driven model and give merchants direct access to agent‑driven sales.

Agentic Ad‑Free Shopping Browser Extension

Summary

  • Browser extension that strips ads, tracking, and intrusive upsells from e‑commerce sites while exposing a clean DOM and an API for AI agents to interact with the site in a human‑like manner.
  • Core value: Lets agents bypass anti‑bot measures and avoid being blocked, while giving users a cleaner shopping experience and protecting them from manipulative dark patterns.

Details

Key Value
Target Audience Everyday shoppers who use AI agents, privacy advocates, developers building agentic workflows
Core Feature Content‑script based ad blocker + agent API (e.g., window.agentAPI = {click, fill, navigate}) that runs in the page context, plus optional local LLM for intent parsing
Tech Stack Manifest V3 extension (JavaScript/TypeScript), Webpack, optional Rust via WebAssembly for performance, uses Chrome Storage for rules
Difficulty Low‑Medium
Monetization Hobby

Notes

  • HN users lamented Amazon’s worsening search and dark patterns (“Amazon actively prevent you finding what you want”) and wanted agents that help users find what they want without manipulation.
  • By giving users control over the agent API and stripping manipulative content, the extension reduces the incentive for sites to block agents and improves agent success rates.

Legal Compliance Checker for Agentic AI

Summary

  • SaaS/tool that ingests a target website’s Terms of Service, robots.txt, and API policies, then analyzes whether a proposed agent action (logged‑in browsing, screenshot scraping, headless interaction) is likely permissible under CFAA, CDAFA, and related statutes, outputting a risk score and mitigation suggestions.
  • Core value: Gives AI agent developers confidence to innovate without inadvertently violating computer‑fraud laws, reducing legal friction and costly litigation.

Details

Key Value
Target Audience AI startups, agentic AI product teams, legal/compliance officers
Core Feature Automated policy parser + rule engine (based on precedents like Van Buren, HiQ, eBay v. Bidder’s Edge) that maps technical actions to legal risk categories
Tech Stack Python backend, NLP (spaCy/LLM) for ToS extraction, PostgreSQL, React dashboard; optionally containerized via Docker
Difficulty High
Monetization Revenue-ready: Subscription $99/mo per team (or $5 per domain scan)

Notes

  • The discussion highlighted concerns about CFAA/ToS violations (“If web scraping is legal then hitting the public api Amazon shouldn’t also be legal?”) and the Perplexity case where Amazon alleged unauthorized access.
  • Provides concrete guidance that HN commenters would appreciate, potentially preventing lawsuits like Amazon’s injunction request and fostering safer agentic development.
