Agentic payment rails
Can an agent complete a purchase without a human at the keyboard?
Why it matters
A shop that an agent can browse but not pay stops one step short of the point. The rails are young and picking one is a real decision, but the shops that ship first will be the ones agents can actually buy from.
How to fix it
Evaluate x402, the Agentic Commerce Protocol and the Universal Commerce Protocol against your payment provider, then publish the discovery document for whichever you adopt.
