Swap letter case for deterministic transform tests. Call when you need a pure case flip without locale rules. Returns case-swapped text for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.
