Tx Value Wei → ETH API for agents
Convert a transaction value wei field into ether for display. Call when summarizing transfers from raw tx objects without RPC. Returns eth amount from wei value 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.
