SDK & API

The demo evaluate endpoint reads the seeded Acme catalog. Console edits stay in the browser; the public API always evaluates the published seed so it works on the server.

const res = await fetch("/api/evaluate", {
  method: "POST",
  headers: { "content-type": "application/json" },
  body: JSON.stringify({
    flag: "new-checkout",
    environment: "production",
    userId: "user-42",
  }),
});
const { enabled, reason } = await res.json();
if (enabled) renderNewCheckout();
