Hyperliquid Funding Radar: a one-page, read-only dashboard of every Hyperliquid perpetual, for traders hunting funding and open-interest extremes. Publish it under the site name hl-radar.

Data: only the public Hyperliquid API, called from the browser (POST https://api.hyperliquid.xyz/info, CORS is open). No backend, no wallet connect, no API keys.

• Main table from {"type":"metaAndAssetCtxs"}, refreshed every 30 s: coin, mark price, 24 h change (vs prevDayPx), funding per hour and as APR (hourly rate x 24 x 365), open interest in USD (openInterest x markPx), 24 h volume in USD (dayNtlVlm), premium.
• Sort by any column; search by coin; filters: minimum 24 h volume (default 1M USD), only positive or only negative funding.
• Colour funding APR on a scale: negative funding (shorts pay longs) in red, positive funding (longs pay shorts) in green, stronger colour for larger values; mark the top 5 and bottom 5 funding coins.
• Clicking a coin opens a detail panel: 7-day funding history from {"type":"fundingHistory","coin":...,"startTime":...} as a bar chart (APR), and 7-day hourly price candles from {"type":"candleSnapshot","req":{"coin":...,"interval":"1h","startTime":...}} as a line chart, plus average and current funding APR.
• Header summary: total open interest, total 24 h volume, number of coins with funding above +50% APR and below -50% APR.

Look: a dense trading-terminal style, dark by default, monospaced tabular numbers, one accent colour; no stock images.

Pages must work well on a phone (the table becomes cards) and in dark and light mode (follow the system, with a toggle). Show "updated N s ago" and a clear error state if the API does not answer. Footer: "Data: Hyperliquid public API. Not financial advice." English UI.
