Why AI transactions are different.

Suppliers have APIs. Agents can call APIs. So why is completing a purchase still the hard part?

Every supplier becomes another engineering project. Four builds, four sets of edge cases, four ways for a purchase to fail.

Adding the fifth supplier is not your project. It is ours, and it changes nothing in your code.

Five things an API gives you, and five things it doesn't.

A supplier API is built for a developer who already agreed the commercial terms, already has an account, and is writing code by hand. An agent has none of that.

The gapWhat an API assumesWhat an exchange has to do
Who is allowed to buy That whoever holds the key is authorised, because a person set it up. Prove the agent is acting for a real buyer, within limits that buyer set, and refuse it the moment they change their mind.
What the price means That a developer will read the documentation and work out what is included. Turn every supplier's pricing into the same shape so two options can be compared without a human interpreting them.
Whether it's allowed That your application already decided this before calling. Apply the buyer's policy and the supplier's eligibility rules before an option is ever offered, and say why when something is excluded.
How money moves That you have an account, a contract, and a card on file with each supplier. Pick a payment method per purchase, cap it to what was authorised, and settle it where the finance team expects.
What happens when it breaks That a person is watching, and will retry or call someone. Return a failure the agent can act on, guarantee it never books twice, and leave a record of what was attempted.

There is a reason payments ended up as networks and not a thousand direct integrations.

Every card transaction could in principle be a private arrangement between a merchant and a bank. It isn't, because agreeing the same rules over and over costs more than shared infrastructure.

Agent commerce is at the same point, about fifteen years earlier than it feels.
