JSON Escape API for agents
JSON-escape a string (without surrounding quotes). Call when you embed text into a larger JSON template safely. Returns escaped string body 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.
