Build vs buy · AI agent checkout

OrderCore vs Stripe + a custom order backend

Stripe is a great payments API. But "let my AI agent buy something" is not just a payment — it's a catalog, an order record, idempotency on retries, and webhooks. Here's what you actually sign up to build if you start from Stripe alone, and where OrderCore's agent commerce API shortcuts it.

What "agent checkout" really requires

The moment an autonomous agent can retry a tool call, checkout stops being a single API call and becomes a state machine. A network blip during "complete" must not create a second order or a second charge.

The fastest way to judge the difference is to run the demo — it creates a checkout session, completes it into an order, then retries the same session to prove you get one order, not two. Runs offline in mock mode, no signup.
