Basis Percent API for agents
Basis percent = (future − spot) / spot for carry checks. Call when cash-and-carry or premium/discount scans from caller prices. Returns basis percent 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.

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