What Are Agentic Payments?
Agentic payments are payments an agent initiates — not a human. The protocols exist; the safety layer is what's missing.
The protocols
x402 — HTTP-based agent payments using the 402 status.
AP2 — Google's agent payments protocol.
AgentKit — onchain agent payments.
The difference from human payments
No human reviews each payment — speed is the point.
Fast settlement means fast damage if something goes wrong.
The control layer
A pre-spend firewall sits between the agent and the rail: APPROVED, BLOCKED, or FLAGGED before settlement.
FAQ

Emerging — the rails are live, adoption is growing. Controls are the constraint.
Who needs to care now?
Anyone deploying agents with payment capability — which is any agent with a tool that spends.
