Automaton Token Safety

FREE, runs locally. Lint any x402 paid endpoint for protocol conformance: HTTP 402 challenge, x402Version, accepts[] (exact scheme), Base network and addresses, EIP-712 domain, and rejection of malformed, forged, expired, underpaid and wrong-recipient EIP-3009 payments. Returns verdict, grade and per-check results.

FREE, runs locally against Base Mainnet RPC. Dry-run a transaction before sending it: eth_call + eth_estimateGas at the latest block. Predicts whether it will revert and decodes the reason (Error(string), Panic(uint256) codes, custom-error selector, or node rejection such as insufficient funds). Returns { ok, willRevert, revertReason, estimatedGas, returnData }.

PAID 0.001 USDC/call, or free trial (3/day/IP). Bytecode security scan of a Base token contract: honeypot opcodes, mint/blacklist/pause/tax capabilities, a risk score and a verdict. Read-only — no transaction is sent. On 402, pay the accepts[] terms then retry with the payment tx hash. (Exposed as `security_scan` on older clients.)
