Get Depth For Coin

Per-coin depth history (rolling, up to 24h). Free: BTC only; Pro + Pro Plus: any tracked coin.

Tracked universe is the top 25 Hyperliquid perps by 24h notional (re- selected each sweep), not every coin — an untracked coin 404s. The current set is the coins list on /liquidity/depth.

minutes is a time window measured back from now, not a row count. Sampling runs on a ~2-minute timer and can skip, so count is the number of snapshots that actually landed in the window — expect roughly minutes / 2, fewer after a stall. Each record carries ts so staleness is visible.

Each record carries depth_usd.bid / depth_usd.ask per band (10/25/50/100 bps) plus imbalance_10bps. levels_truncated flags, per band per side, when the deepest level in HL's ~20-level snapshot still sat inside the band — that band's depth_usd is then a lower bound on the true resting depth, not the depth.
