pacta_check_preflightOne-call pre-execution safety check of a contract before an agent interacts with it: verdict (immutable / timelock / zero-delay timelock / multisig / EOA admin / unclassified / undeployed), 0-100 risk score, proxy + implementation, controller kind, zero-delay upgradeability and…
pacta_scan_control_planeLive control-plane scan of an EVM contract: EIP-1967 implementation/admin/beacon, owner(), Safe threshold/owners/guard, timelock delay, code size and deterministic risk flags at the latest (or a given) block. Free during the launch (no key, no payment).
pacta_scan_timelock_opLive OpenZeppelin TimelockController operation state: isOperation/Pending/Ready/Done, getTimestamp (ETA), getMinDelay at the latest block. Free during the launch (no key, no payment).
pacta_scan_proposal_diffRe-runs the pinned contract reads of a Pacta-tracked governance proposal (Aave, Euler, Morpho, Sky) at the live block and returns pinned-vs-live diffs. Free during the launch (no key, no payment).
pacta_get_live_timelocksLive state of the public pending timelock operations tracked in https://pacta.wtf/api/v1/radar.json, each re-checked at the latest block (getTimestamp, isOperationPending, isOperationDone). Free during the launch (no key, no payment).
