Object Pick Exists API for agents
Pick only keys that exist on an object. Call when you whitelist agent fields without inventing missing keys. Returns object, missing, count 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.

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