The emerging category where AI agents — not humans — browse, compare, negotiate, and transact on a user's behalf. Stripe, Shopify, Anthropic, and OpenAI are all building protocols and payment rails for it (Stripe's Agent Toolkit, ACP, etc.). The strategic implication: product pages optimized for human eyeballs will matter less than machine-readable catalogs, structured data, and trust signals that agents can verify. For FeatureOS and SupportWire, the adjacent question is whether support and feedback also become agent-to-agent — and how the product surface needs to change when the "user" is another model.
