Pay-per-call token risk check for Base
Pay-per-call token risk check for Base: send a Base ERC-20 contract address, get deterministic JSON risk flags (owner/renounced, upgradeable proxy, mint/pause/blacklist/fee functions, on-chain Uniswap v2/v3 + Aerodrome liquidity, holder concentration) and a rule-based risk_level. Use before buying or listing an unfamiliar Base token. $0.01 USDC. Invalid input returns 400 and is not charged. Not financial advice.
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.
