Hyperliquid pre-trade risk check API. Full pre-trade check of a Hyperliquid perp order: everything in lite (verdict, rule issues with fixes) plus the isolated liquidation price and distance, taker impact and average fill from the live L2 book for market orders, funding carry per day (who pays), mark/oracle premium, open interest and size vs 24 h volume. Read-only; never places or signs orders. Fail-closed. Not financial advice; the exchange decides whether an order is accepted.
