The core insight is that discovery benefits from non-determinism (LLMs), but payments and credentials require strict determinism. Three solutions are demonstrated: shared payment tokens (scoped credentials with spend limits tied to specific sellers, enforced by Stripe), the machine payments protocol (HTTP 402-based payment signaling for API tool calls, with blockchain settlement via Tempo), and the agent-to-commerce protocol (ACP, built with OpenAI) providing structured JSON-based checkout flows so agents can transact without scraping web UIs. Together these minimize blast radius from agent errors like buying from wrong merchants, wrong amounts, or leaking credentials. ## Full article daily.dev links to this article rather than hosting it.
