Api Endpoint

ERC20 pre-trade safety check

Use when an agent must decide whether to touch a token at all: a pre-trade risk check 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. It returns the EVIDENCE - the exact selector found and its byte offset - so an agent can apply its own policy. Deterministic: same contract, same answer.
