Get Volume Scanner
GET/v1/cryptodata/volume/scanner
Every Hyperliquid perp with its 24h volume, 30-day average, and multiplier. ``multiplier`` = live rolling-24h notional ÷ mean daily notional over the last 30 **settled** days (today's partial day is excluded from the baseline). A reading of 3.0 means the coin is trading at three times its normal daily volume. ``multiplier_median`` is the same ratio against the 30-day median, which is far less distorted by a single prior blow-off day — compare the two when a coin's recent history is lumpy. Perps listed less than 7 days ago have no honest baseline and report ``multiplier: null`` with ``band: "unknown"`` rather than a spurious number. Example screens: `?min_multiplier=3` (today's unusual activity), `?band=dormant` (coins that have gone quiet), `?sort=volume_24h` (plain volume leaderboard). **Tiers:** Free returns the top 20 perps by 24h volume; Pro / Pro Plus return the full universe.
