Margin Required API for agents
Margin required for a notional at a given leverage. Call when pre-trade margin checks without exchange APIs. Returns margin required 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.
