Token Pre-Trade Check

Honeypot and rug check before a trade, built for trading bots that check every token in a loop: up to 5 token addresses per call (Base, Ethereum, BSC, Arbitrum, Polygon, Avalanche, Optimism or Solana), one decision each: ALLOW, CAUTION or BLOCK, with grade A to F, score, honeypot flag and the main reason. Based on our own on-chain checks (contract code, pools, real buy and sell simulation). Results are cached for 10 minutes, so repeat checks answer in milliseconds. Accepts token, tokenAddress or tokens. Cheaper per token than any single-token verdict.
