Use the AI Fear Index in your own work

The index is free to cite and embed. Two integration points: a JSON endpoint with the full signal breakdown, and a live SVG badge for READMEs, dashboards and posts. Values refresh roughly every 15 minutes.

Live badge

A dark card showing the current score and band. Drop it into any HTML page or Markdown file — it links back to the live index.

Markdown

Embeddable live gauge

The full semicircular gauge as an iframe — updates itself every ~30 minutes and links back to the live index. Light and dark themes.

JSON API
