Realized PnL (FIFO lite) API for agents
Lite FIFO-style realized PnL from sequential buy/sell fills. Call when attributing closed PnL from a short fill tape without a full OMS. Returns realized pnl summary from fills 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.
