Embed

Pay with Fulcrum, anywhere

One iframe turns any page — or any AI shopping agent — into a Fulcrum checkout. The buyer pays from their @handle wallet over x402; your page gets a paid event with the tx hash to fulfill against. No card forms, no PCI scope.

Integration

<!-- Drop Fulcrum checkout into any page -->
<iframe
  src="https://fulcrum.frontierpaymentslab.com/embed/checkout?item=Pro+Plan&vendor=Acme+SaaS&amount=1.99&ref=order_123"
  width="380" height="280" allow="payment"
  style="border:0;border-radius:16px"
></iframe>

<script>
  window.addEventListener("message", (e) => {
    if (e.data?.source === "fulcrum" && e.data.type === "paid") {
      // Fulfill the order
      fulfill(e.data.ref, e.data.txHash, e.data.amountUsd);
    }
  });
</script>

Built for agentic commerce

The same checkout URL returns an HTTP 402 with machine-readable payment terms. A shopping agent can settle it autonomously — within the spend envelope its human authorized — and your fulfillment hook fires exactly the same way.
