POST /v1/market/black-scholes
unprobed
Black-Scholes option price and Greeks (delta, gamma, vega, theta) from JSON keys spot, strike, tau (years; 3-month = 0.25), sigma (annualized volatility), and is_call (boolean). Pure closed-form calculation, no market data looked up or stored. vega is ∂price/∂sigma per 1.0 volatility (not per 1%).
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
