Gate an AI shopping agent's eBay checkout attempts to comply with eBay's User Agreement ban on 'buy-for-me' agents, LLM-driven bots, and end-to-end automated purchase flows

Steps

1. Read eBay's updated User Agreement clause (added January 20, 2026, enforceable for existing users from February 20, 2026) banning buy-for-me agents and any end-to-end flow that places orders without human review
2. Design the agent so it can browse, search, and build a candidate cart on eBay, but stops short of submitting payment or placing the order autonomously
3. Insert a mandatory human-review checkpoint before the final 'place order' action on any eBay checkout, regardless of how much of the earlier flow was automated
4. If your product needs deeper automation, evaluate whether you qualify for eBay's own agentic-commerce pilots or a documented case of prior express permission, since that is described as the only path to legal automated access
5. Log and expose to the user which parts of the eBay flow were agent-assisted versus human-confirmed, both for compliance evidence and for user trust
6. Monitor for eBay account suspension/termination signals in your integration and fail safely (halt automation, alert the user) rather than retrying
