The Verge reported on 17 October that users of AI agents, tools that act online for a person, are hitting blocks on major sites. It named Meta's Muse, xAI's Grok, OpenAI's Dots and Instinct. Yelp told TechCrunch it admits only agents that pay for its data licensing program, The Verge said. Delta Air Lines stops agents from booking tickets for users. JPMorgan Chase and Charles Schwab confirmed they keep agents out of accounts for security reasons. Amazon said Muse's continued access breaks its site policies, according to The Verge. Separately, a court docket shows Amazon filed an amended complaint against Perplexity AI on 21 September 2026.
Much is still open. The docket entry lists 16 attached exhibits but does not show what the amended complaint argues. The Verge says some users found Cars.com and Amtrak no longer work with their agents. It suggests those firms may be blocking quietly, but neither company's response is given. The sources do not say how many sites block agents. The Verge says a judge ordered Perplexity to stop its agents shopping on Amazon, and an appeals court overturned that order in August. Meta said it would rather work with businesses than fight, and has partnered with retailers including Walmart, Gap, Sephora and Best Buy.
For teams that build or buy agent tools, access to a site is not guaranteed. Each site sets its own terms, from paid licences to outright bans, and those terms can change.
