Paid by Agents from the team behind AgentCheckout.org

The machines started paying. Someone should keep the receipts.

One email a month on agentic payments — what actually shipped across AP2, ACP, UCP and x402, who's winning the protocol race, and what it means if you sell things for a living.

Neutral. Sourced. No vendor spin. Ten minutes, once a month.

What lands in your inbox

The space moves monthly. Corporate blogs each tell you their protocol is winning. We keep score instead.

The ledger

Every launch, pilot, partnership and standards move of the month — AP2, ACP, UCP, x402, Visa TAP, Mastercard Agent Pay — in one scoreboard. What shipped vs. what was press-released.

One deep read

A single analysis that would take you a week to assemble: protocol comparisons, adoption data, liability questions nobody has answered yet. Written to be cited.

The merchant angle

The part everyone else skips: what this means if you actually sell things. Discoverability, checkout friction, agent traffic policy — concrete moves, not thought leadership.

Written for people with money in motion

Fintech operators tracking the protocol race. Developers wiring agents to payment rails. Merchants and SMB owners wondering when an AI agent will show up at their checkout — and whether they'll be ready when it does.

Every issue links to the full guides on AgentCheckout.org, the vendor-neutral reference on agent checkout & payments.
