b4j0x -On-demand smart contract security auditor. Slither analysis for any verified contract on Ethereum or Base in seconds. Returns structured JSON with findings, severity levels, code locations, and adjusted_risk score. Proxy-aware with automatic implementation detection. False positives flagged. Single tool: scan_contract(address, chainId). Stateless, deterministic, no auth — just x402 payment ($0.50 USDC). Ideal for pre-interaction checks, due diligence, or audit triage.
