Stake SOL for a liquid-staking token (non-custodial). amount in lamports. protocol: marinade | jito | blaze. Returns an UNSIGNED base64 tx + the LST received + current APY. The technology service fee is charged on the staked-SOL notional past the daily free tier (x402 payment_header; set pay_in_crank for the $CRANK discount). Workflow: EXECUTE step (yield leg) -- stake the idle slice after comparing get_lst_yields. Non-custodial. Monitor via portfolio_snapshot. See get_trading_workflow. ``idempotency_key`` (optional): a client-generated UUID. Retrying with the same key + same args replays the original result instead of re-staking. Reuse the SAME key across the build call and its ``signed_transaction`` completion call -- the two legs dedupe independently, so this never raises IDEMPOTENCY_CONFLICT; a NEW key means a genuinely new stake. ``signed_transaction`` / ``verify`` (two-phase execution): re-call this tool with the SIGNED base64 tx and Crank broadcasts it, then awaits on-chain confirmation and re-reads the LST + SOL balances -- the response carries a real ``verification`` block ({confirmed, slot, post_state, expected_vs_actual}). Gate follow-on decisions on ``verification.confirmed``, never on tx_signature alone. verify=false skips only the confirmation wait.
