Agentic commerce relies on agent-specific payment rails: tokenized card credentials or wallets scoped to an agent, spending caps enforced outside the model, and a merchant-of-record or processor that can verify the purchase was authorized. Competing efforts include the OpenAI-Stripe Agentic Commerce Protocol (ACP), Google's Agent Payments Protocol (AP2), Stripe Link for agents, Mastercard Agent Pay, and Cloudflare Wallets. Late-August 2026 saw the first reports of live recurring agent spend, including a claimed ~$1,300 per agent per month via Stripe Link.
