The eight brands the platforms put front-and-centre for agent checkout. We check what an AI agent actually finds on their own domain — not the catalogue feed the platform hosts. This page is checked live; it's exactly what our agent sees.

These are the best-resourced, earliest-integrated sellers in agent commerce — and most of them have a bare front door. The platform built the rail and hands over their catalogue, but when an agent lands directly on the brand's own domain, there's often nothing for it to read. If the gap is this wide for the launch partners, it's wider for everyone else.
Note the honest nuance: this isn't “they do nothing.” Some publish an llms.txt. But none expose the actionable agent.json an agent needs to know what it can do — browse, price, buy, contact — which is the difference between being described and being transactable.
