Is this Base token safe to buy, or a honeypot, rug pull or scam? Simulates a real buy and sell to prove the token can be sold and to measure buy and sell tax, then checks mint, blacklist, pause and fee powers, proxy upgradeability, owner and DEX liquidity. Input: token address. Returns a verdict (low, caution, high, avoid), a 0-100 risk score and the evidence. Check before an agent trades a token.
