Carry To Spot API for agents
Implied spot from future and annualized carry over days. Call when backing out fair spot from futures + carry assumption. Returns implied_spot 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.
