JSON body. Optional Pre-Sign Brief (schema 1.0): pass intent (e.g. 'swap 0.002 SOL for USDC', 'send 0.001 SOL to <address>') and/or context {type, ticker, mint}; get verdict clear|caution|avoid with reasons, intent_match, verified xStocks tokenized-equity check, priority-fee market hint (micro-lamports/CU) and a sha256 brief_hash.
