Major Websites Block AI Agents Citing Security and Licensing Concerns
Delta, JPMorgan Chase, and Yelp are restricting autonomous AI tools from accessing their platforms, creating friction for users relying on digital assistants.
Key points
- Financial institutions like JPMorgan Chase block AI agents from accessing accounts due to security risks.
- Yelp requires AI agents to participate in its paid data licensing program to access information.
- Delta Air Lines prevents autonomous agents from booking tickets on behalf of users.
Major websites are actively blocking autonomous AI agents from performing tasks on their platforms. This trend affects services from OpenAI, Meta, Google, and Instinct, which promise agents can handle reservations and shopping. Users report that these digital assistants are increasingly unable to complete actions across top internet services in recent weeks.
Specific companies have confirmed restrictions on agent activity. Yelp told TechCrunch it only allows AI agents that pay for its data licensing program. Delta Air Lines is preventing agents from booking tickets. JPMorgan Chase and Charles Schwab have also confirmed they are blocking AI agents from accessing accounts, citing security concerns as the primary reason for these restrictions.
Legal and Technical Friction
Amazon engaged in a legal battle with AI startup Perplexity last year over agentic shopping features. Amazon sued Perplexity after banning its feature, claiming it repeatedly requested the startup stop allowing agents to shop on its site. Amazon argued that third-party companies purchasing items on behalf of customers should respect service provider decisions regarding participation.
Perplexity countered that Amazon opposes AI agents because they reduce human eyeballs on ads. The startup likened its agent to an extension of the user, arguing Amazon does not believe in the right to hire labor or assistants. A judge initially ordered Perplexity to stop its agents from shopping on Amazon, but an appeals court overturned this ruling in August. Amazon has since filed an amended complaint.
Impact on User Experience
Users of Meta’s Muse, xAI’s Grok, OpenAI’s Dots, and Instinct agents are encountering these blocks. Some users report that sites previously accessible to their agents are no longer working. Cars.com and Amtrak are among the services where users say access has been lost, suggesting other companies may be quietly implementing similar blocks without public announcements.
Even without outright bans, agents may clash with existing anti-bot systems designed to protect websites. This creates technical hurdles for developers trying to ensure their agents can interact with the web. The ongoing legal and technical disputes highlight the growing tension between AI developers and traditional web service providers who control access to their data and transaction systems.
What should you do?
Security and technology professionals should monitor how their organizations handle bot traffic. As AI agents become more prevalent, distinguishing between legitimate user automation and malicious bot activity becomes critical. Organizations should review their web application firewall rules and bot management strategies to ensure they align with business goals while maintaining security.
What to do and how to stay safe: OpenAI
- Review web application firewall logs to identify traffic patterns associated with known AI agent user agents.
- Evaluate current bot management policies to determine if they inadvertently block legitimate automated tools used by customers.
- Monitor official announcements from major service providers regarding their policies on AI agent access and data licensing.
- Test internal automation scripts to ensure they comply with the terms of service of external websites they interact with.
