crypto_funding_cost
Calculate perpetual funding and fee drag
Caller-input perpetual funding cashflow, fees, net carry and linear break-even move. Positive funding: longs pay shorts. Constant-rate scenario, not live rates or a forecast.

crypto_portfolio_stress
Stress a crypto portfolio
Caller-input linear price shocks on up to twenty exposures: P&L, equity and gross asset/venue concentration. Symbols are scenario labels, not live coverage. No liquidation or probability model.

Idempotent
Input schema
{'type': 'object', 'properties': {}, 'additionalProperties': False}
liquidity_tiers
