One-call pre-trade sanity check: 'I want to long $X of SYMBOL — is now sane?' Combines live orderbook slippage at YOUR size, cross-exchange funding (carry cost), open-interest crowding, and contract security (GoPlus) into a single ok/caution/avoid verdict with a per-factor breakdown. Major ERC-20 addresses (LINK, UNI, ARB, OP, AAVE, PEPE, SHIB) resolve automatically; native assets (BTC, ETH, SOL, ...) report security n/a; an unrecognized token without token_address reads 'unknown' and caps the verdict at caution — an unscreened contract can never read 'ok'. Replaces four API integrations and the judgment layer on top of them. Raw component data embedded so you can apply your own thresholds.
