Before an AI agent can recommend or buy from your store, it moves through a stack of machine-readable layers, from a file at your domain root down to the checkout instructions. AI Commerce Infrastructure is that stack. It is the plumbing of agentic commerce.
Most store owners think about one layer at a time. They add schema, or they hear about llms.txt and turn it on. But an AI agent does not experience your store as separate features. It moves through them in sequence, and a gap in any layer stops it before it reaches the next. Infrastructure is the right way to think about it: a stack where every layer has to hold.
From first contact at your domain root down to a completed purchase, here is the order an agent travels in and what lives at each layer.
The free AI Commerce Score checks each layer of your stack and shows where an agent would stall on the way to recommending you.
