Drop a HotBirthdays profile card into your blog post, fan wiki, or newsletter. One script tag, no API key, zero JS bundle on your end.
Paste the script once anywhere on the page (footer is fine), then drop an anchor with data-hb-embed set to the profile's slug wherever you want the card to render.
<a data-hb-embed="sontungmtp">Son Tung MTP</a> <script src="https://hotbirthdays.com/embed/widget.js" async></script>
The script swaps every tagged anchor for an iframe pointing at our profile embed page. If the script fails to load, the original anchor stays — visitors still get a working text link.
Same iframe the script swaps in, rendered here against Tian Xiwei.
If you can't add a script (CMS quirks, AMP), embed the iframe directly. Same content, no JS.
