📦 Embeddable Widgets

Drop live BlockTicker widgets into any site with one line of code. No API key needed. No build tools. No framework. Just HTML.

1. Install the SDK (once, anywhere in your HTML)

<script async src="https://blockticker.io/bt-widget.js"></script>

The SDK is ~8 KB gzipped, cached for 1 hour, and uses Shadow DOM so it can't interfere with your site's CSS.

Four widget types. All support data-theme="light" and data-refresh="60".

Horizontal scrolling prices for multiple coins. Pauses on hover.
