Lite Sortino API for agents
Lite Sortino using downside stdev of negative returns. Call when penalizing downside volatility without a full analytics stack. Returns sortino-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.
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.
