One line of HTML puts a live dealer-gamma chart for any US ticker on your page. Net GEX by strike, the zero-gamma flip, call wall and put wall — recomputed off the options chain through every session, so you never touch it again.
Both lines matter. The iframe draws the chart. The link underneath is the attribution — please keep it, it is the only thing we ask for in exchange, and it is what makes this free for everyone.
Why the link sits outside the iframe. An anchor placed inside an iframe is a link from our own domain to itself, so it does nothing for you or for us. The attribution has to live in your page's HTML to mean anything. That is why the snippet is two elements rather than one — it is not a formatting accident.
It maintains itself. The chart reads the live options chain, so a widget embedded today shows today's levels and next quarter's levels without you republishing anything.
No key, no signup, no rate card. There is no account to create and nothing to expire. If you would rather have the numbers than the picture, the same data is on the free API at /v1/gamma/{ticker} — also keyless.
It works anywhere an iframe works. WordPress custom HTML blocks, Ghost, Webflow, Substack, Notion, plain HTML. Set theme=light or theme=dark on the URL to match your site, or leave it off to follow the reader's system setting.
A ticker page or a stock write-up, where the gamma structure explains why price keeps stalling at the same strike. A weekly market note, where the flip level gives readers something concrete to watch. An options-education post, where a live chart beats a screenshot that is stale the day after you publish.
If you write about options and want a variant we do not offer yet — a different size, a specific expiry, IV instead of gamma — email me and I will build it. That is a genuine offer, not a form.
/embed/gex/{ticker} — any US-listed optionable symbol.
?theme=dark or ?theme=light — defaults to auto.
Height: 420px suits most layouts; the chart scales to whatever width it is given.
Full per-ticker pages live at the gamma map, and the SPX read is at /spx.
