Black-Scholes d1 d2 API for agents
Compute Black-Scholes d1 and d2 from spot/strike/vol/time/rate. Call when you need BS inputs for Greeks without a market feed. Returns d1 and d2 as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
