Three live widgets in six shapes: a liquidation heatmap, cross-exchange perpetual
funding rates, and the Fear & Greed Index. Pick one below, copy the snippet, paste it
anywhere HTML is allowed. It is a plain <iframe> — no JavaScript to
install, nothing that tracks your readers, and nothing that expires.
Several wordings are offered on purpose — see how the link works. Change the caption to your own sentence once you have pasted it; that is better for both of us than thousands of identical captions.
The snippet is yours to edit. Change the width, the wording, the margins — it is ordinary HTML and nothing in the widget checks what you did to it.
The snippet includes a small grey line of text outside the iframe with two links: one to the page the data comes from, and one to us. That line is the price of the widget, and we would rather say so plainly than bury it in a licence. Search engines cannot see links that live inside an iframe, so a widget whose only credit is in the frame is worth nothing to us — this line is the whole reason we can give the widgets away.
What we deliberately do not do, because Google's link-spam guidance names it and because it would be dishonest anyway:
rel="nofollow" or rel="ugc", that is
completely fine. The widget behaves identically, we do not check, and nothing
degrades.If you would rather not carry any link at all, please just use the free API directly and build your own chart. That is a legitimate option and it is documented.
The liquidation heatmap plots forced liquidations actually reported by Binance, OKX, Bybit, Bitget and BitMEX. Nothing is modelled, estimated or back-filled. When a market is quiet, the widget says the market is quiet.
No widget will ever tell your readers to buy or sell. We have published six pre-registered studies that found no durable directional edge in this data — see methodology. A widget travels without its disclaimer, so it carries no claim to begin with.
If our origin is unreachable the widget keeps the last real snapshot and stamps it with its true UTC time, or says in words that it cannot load. Your readers never see a blank box or a made-up number.
No Tailwind, no Chart.js, no webfont, no analytics, no cookies. Fixed
width and height so it causes no layout shift, and loading="lazy"
so a below-the-fold embed costs your readers nothing.
Choose light, dark, or auto. Auto follows each reader's own system setting, so the widget looks native on a light blog and a dark one without you configuring anything.
Every widget is free with no account. Symbols are BTC, ETH and SOL, matching the free API tier. If you need more, the paid tiers cover the API — the widgets stay free either way.
Anywhere raw HTML is allowed: WordPress (Custom HTML block), Ghost (HTML card),
Webflow, Squarespace, Notion (use Embed with the iframe URL), Discourse,
and any hand-written page. There is no <script> in the snippet
precisely because most content platforms strip script tags.
If your platform only accepts a bare URL rather than an iframe, use the widget URL by itself — but note that the caption line, and therefore the link, will not come with it, so please add your own credit.
