agent402.tools/api/skill/contract-audit

Bundled execution of the Contract audit workflow - Triage a smart contract before an agent interacts with it: verified Solidity source, heuristic vulnerability scan, known-address check, function-selector resolution, and a read-only dry-run of the exact call you plan to make. One x402 payment runs 5 underlying tools (contract-source, solidity-scan, selector-lookup, address-label, tx-simulate); partial-success per step.
