Bridge Cost Budget API for agents
Sum gas + bridge fee + slippage budget into total cost. Call when comparing bridge routes with known component costs. Returns total_cost and components 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.
