EndpointOrder book liquidity of one coin: resting USD per price bucket for every covered venue (Hyperliquid l2Book in a fine layer ≈ ±2 % and a coarse layer ≈ ±10–25 %, Binance / Bybit local books within ±5 %), depth within 1 / 2 / 5 % and the bid/ask imbalance, plus walls (large resting liquidity relative to the buckets around it) that are active or ended in the last hour. Status pulled = removed before the price touched it, filled = the price traded into it. Walls cannot be attributed to wallets and a pulled wall is not proof of spoofing. With hours also the book heatmap over time (paid plans). Free keys: BTC, ETH and HYPE, current book only. Distances are fractions (walls[].distance, depth[].band; the older …Pct names hold the same fractions). Coins without a Hyperliquid market answer 404. Licence review: Binance / Bybit books and walls are withheld (meta.restricted); venue=binance|bybit answers 403 source_restricted.
