  "description": "JSON Object Pick: JSON Object Pick keeps selected top-level keys from one JSON object from bounded caller-supplied values without an external provider. Call JSON Object Pick before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for JSON Object Pick as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Processes bounded caller-supplied data in memory only; it performs no file fetch, database write, code execution, or retention. Advisory output only; the buyer owns authorization, payment policy, and production decisions.",
