Given any public HTTP(S) URL, returns a measured liveness verdict - LIVE, PAUSED, GATED, CHALLENGED, DEGRADED, DEAD or UNKNOWN - with every reason carrying the source it was read from.

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.
