Pre-action check for AI agents: inspect an unfamiliar live x402 v2 challenge immediately before purchase. Verify price, network, payee, resource binding, timeout, and Bazaar metadata without paying the target or forwarding credentials. POST probes send only a fixed empty JSON object; callers cannot supply target request content.
