CardFax + Lovable, Claude & AI builders

Tell your AI to add CardFax. That's the integration.

Building with Lovable, Claude, or any AI coding platform? The integration is a prompt. Paste the block below into your builder's chat and it wires the widget correctly — script once, widgets where they belong, no restyling of the internals.

What shops build with it

Vibe-coded storefronts

AI-built shops get the same registry proof as hand-built ones — the widget is plain HTML, which every AI builder speaks natively.

Custom apps on the Registry API

Point your AI at the Registry API instead and it can build bespoke views — same key, same meter, your design.

The integration prompt

1.Copy the integration prompt below.
2.Paste it into your AI builder's chat, with your key and card serials filled in.
3.Review the change it makes and publish.

Add the CardFax registry widget to my site.
1. Load the embed script once, before </body>:
   <script async src="https://cardfax.com/embed/v1.js" data-key="MY_CARDFAX_KEY"></script>
2. Where a slab should show verification, render:
   <div data-cardfax="verify" data-serial="THE_CARD_SERIAL"></div>
3. For a full record card use data-cardfax="card"; for my whole graded
   inventory use data-cardfax="inventory" (options: data-sport,
   data-min-grade, data-limit).
The widget styles itself (Shadow DOM) — do not restyle its internals, just
position the container. After a route change, call window.CardFax.scan().

The prompt teaches any AI builder the correct integration in one message.
