🟢check_perp_order(coin, side, size, notional, price, ...)
Checks a Hyperliquid perp order BEFORE your agent sends it: would the exchange reject it, and what does it cost and risk? Give coin, side and size (coins, as you would send it) or notional (USD); optional limit price (omit = market order), leverage, margin cross/isolated, reduceOnly. Returns verdict REJECT_LIKELY / CAUTION / OK, issues[] with fix values (size decimals, price tick, $10 minimum, max leverage by margin tier, isolated-only, OI cap, delisted, far-from-mark), warnings[], rules, isolated liquidation estimate and distance, taker impact from the live L2 book, funding carry per day, market facts, confidence and sources_failed. Read-only: never places, signs or holds orders and needs no keys. Free: 30 calls/day per IP with full results (max 10/min; invalid input is not counted). After that the tool returns an error with the x402 pay URL ($0.01 USDC per full check at /v1/full, or $0.003 lite at /v1/lite) or prepaid credits. Not financial advice; the exchange decides whether an order is accepted. PerpCheck is a read-only pre-trade check: it never places, signs or holds orders, has no custody and never asks for keys.
