Black-Scholes Delta API for agents
Call/put delta from BS closed form. Call when delta-hedging or option inventory needs BS delta. Returns delta for call and put 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.
Intent to transaction
One command, attributed.
The source header follows this discovery route through challenge, payment and delivery without exposing the buyer or request body.
