Token risk score API: deterministic 0-100 rug-check for ERC-20s on Ethereum, Base, Polygon, Arbitrum, Optimism, BSC, and Avalanche. Combines on-chain reads (bytecode, symbol, decimals, supply), DefiLlama price + confidence, and Etherscan verification and age. Published rubric, no AI: start 50; no bytecode=0; +15 price (+10 confidence>=0.9); +15 verified source (-10 unverified); -10 zero supply; -5 odd decimals; +10 age>=180d, -15 age<7d. NOT financial advice.
