Description and use

<p><em>Disclosure: we build Pink Agentic AI Payments at PinkWallet. The video below is one continuous, unedited screen recording of a real n8n 2.43.x instance talking to our sandbox. Nothing is cut, sped up, or staged.</em></p> <p>If you've wired a payment tool into an n8n AI Agent, you already know the uncomfortable part: the agent can call that tool with any number it wants. A system message telling it to "stay under $200" is a suggestion the model can forget, misread, or talk itself out of. <strong>Pink Agentic AI Payments checks every payment an n8n AI Agent requests against your spending
