Why does my store refuse the cart but not the product page?
Because bot protection usually scores requests that change something, like adding to a cart, more strictly than page views. The product page was let through and the cart request was not, so the agent got as far as choosing a product and no further.
Why it happens
Bot protection often treats the cart request differently from the product page. A page view is let through, while a request that changes state, such as adding to a cart, is scored more strictly and answered with a challenge. A shopper in a browser solves it without noticing; an AI agent cannot solve a challenge at all.
Firewall and rate limit rules do the same thing from a different direction: a rule written to stop cart abuse refuses the request from an automated browser, and the page shows nothing, so the agent is left with a product it chose and no cart to put it in.
This comes up at the Buy stage. The full treatment, including how to reproduce it and what to change, is on The store refused the agent’s add to cart.
