GET /api/contract-gate
unprobed
Pre-trade contract safety gate: static analysis of verified Solidity source + on-chain metadata. Returns pass/fail verdict + red flag checklist (reentrancy, unchecked calls, owner privs, delegatecall, oracle single-point, rug vectors, age). Pay-per-check: 0.25 USDC on Base via x402. Source: Blockscout + Base RPC (public data only).
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
