Agent Check API
Due diligence on an ERC-8004 agent before you pay it or call it: live services and their health, metadata completeness, onchain feedback count and score, wallet activity, concrete red flags, and a usable/caution/avoid verdict with a 0-100 score. Call it when you must decide whether another agent is safe to transact with. Params: chain (default 8453) and agent_id (ERC-8004 token id).
