US appeals court allows Perplexity's AI shopping agent back on Amazon

A US appeals court has overturned an injunction that previously blocked Perplexity from using AI shopping agents to interact with Amazon. The court ruled that the startup’s software does not violate access restrictions because it is the users, rather than the company, who are technically accessing the retail site. This decision marks the first federal appellate ruling on whether AI agents can legally operate on third-party platforms on behalf of consumers. The outcome establishes a significant legal precedent for how AI tools may navigate and interact with online marketplaces.
