What is an Agentic Payment?

An agentic payment is a payment initiated by an autonomous AI agent on behalf of a user or organization — with the agent deciding when, how much, and to whom to pay.

How it works

Agents trigger payments through machine rails — x402 (HTTP-based), Google AP2, Coinbase AgentKit — or directly through vendor APIs.

The agent makes the spending decision; the rail settles it.

Why it's risky

The agent is following a prompt, not judgment. A retry loop, hallucination, or prompt injection can turn one intended purchase into many.

Rails move money fast; there's no human to say 'stop' mid-loop.

The control layer

A spend firewall sits between the agent and the rail: every proposed payment gets APPROVED, BLOCKED, or FLAGGED before settlement.

FAQ

Is an agentic payment the same as an API payment?

No. An API payment is a fixed integration; an agentic payment is a decision the agent makes at runtime — which is exactly why it needs runtime controls.

Do agentic payments require human authorization?

Not by default — that's the point. Controls (approval thresholds) can require it for flagged amounts.
