The pattern where an AI agent, not a human, searches, evaluates and completes a purchase on the user's behalf.

long_def

Agent-as-buyer is the demand side of agentic commerce: the agent compares options, makes the decision and transacts, with the human authorizing scope in advance. It changes optimization targets — product data must be machine-parseable, APIs and structured feeds matter more than visual merchandising, and checkout must accept protocols like ACP, AP2 and x402. McKinsey has projected agentic commerce could reach $1 trillion in US retail by 2030.

Unlike agentic commerce as a whole, which spans buying and selling, agent-as-buyer names specifically the demand-side actor — the purchasing agent whose needs reshape product data, feeds and checkout toward machine-readability.

example

Agent-as-buyer is why a merchant must expose machine-readable product data and an agent-acceptable checkout; the buyer it must win over is increasingly software, not a human shopper.
