Plexa /v1/pretrade/check — pre-trade token safety check on Base: can you still sell this token? avoid fires only on a trap proven on-chain now: no pool to exit into, an exit pot under 5% of your size, or the trading gate off (the honeypot shape). A drained pot is what a rug leaves behind — measured, not predicted. clear = no provable trap, NOT safe. risk_profile: token age, holder concentration, liquidity, transfer limits. Not financial advice.

The post-trade check everything else skips: given a token, your position size and (optionally) entry price, returns live price & P&L, whether the position can still be EXITED at that size, and the token's current rug score — combined into a healthy / watch / exit_now verdict with reasons. The risk that changes after you buy is exactly the risk holders miss.
