Wei to Ether Converter API for agents
Scale wei integer strings into ether for dashboards and receipts. Call when displaying balances, receipts, or logs that arrive in wei. Returns eth float plus wei string 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.

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