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.

Polymarket prediction-market listings. Query: ?limit=1-100. Source: Polymarket Gamma API (free).

Polymarket trader skill score — pure JSON for agents. POST {wallet}. Returns skill_score (0-100, Sharpe-weighted by confidence), classification (sharp/neutral/retail), win_rate, sample_size, max_drawdown, realized + unrealized PnL. No lot reconstruction — for batch screening top holders before entering a market or mirroring a copy-trade.

Computes riskScore, riskLevel, volatility, sharpe, maxDrawdown, concentrationHHI, diversification, effectiveHoldings plus per-rule findings with fixes and sector/position breakdown.

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.
