Decision-grade token trade-safety verdict for a Base ERC-20 in one call
Decision-grade token trade-safety verdict for a Base ERC-20 in one call: SAFE | CAUTION | AVOID plus risk_score (0-100) and reasons, bundling honeypot/sellability simulation, owner-renounced + mint/pause/blacklist/fee-setter/upgradeable-proxy checks, token symbol/name/decimals, and Uniswap v3 WETH-pool liquidity (USD). Replaces many RPC calls and prevents a bad trade. Use when an agent is about to buy or swap a Base token and needs a SAFE/CAUTION/AVOID decision.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
