https://flat-rate-llm.kikoribera03.workers.dev/v1/evm/token-safetyOverview
Pre-trade risk check for any ERC20 on Base, Ethereum, Polygon, Arbitrum or Optimism, straight from the deployed bytecode and live state. Detects mint, pause, blacklist, upgradeable proxy and mutable buy/sell tax powers, and reports whether ownership is renounced. Unlike LLM-written verdicts this returns the EVIDENCE - the exact selector found and its byte offset - so an agent can apply its own policy. Deterministic: same contract, same answer.
