  "description": "Lightweight type/required/property check for agent-held JSON (not full draft validation) — first-party local utility for agent preflight and proven micro-utils expansion. Returns deterministic machine-readable JSON for $0.002 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, no web search, no live RPC, and no mediagen. Results are advisory; the caller owns authorization, budgets, and production controls. Sibling of Delx routes that already converted externally (random, hash, URL, FX families).",
