Lite Sharpe API for agents
Lite Sharpe = mean/stdev of a return sample (no rf, sample). Call when quick risk-adjusted rank of strategy return arrays. Returns sharpe-like ratio and n 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.

One command, attributed.
The source header follows this discovery route through challenge, payment and delivery without exposing the buyer or request body.
