InactiveTool of onyx-paid-mcp
declared in 1.28.0
Pre-flight inspector for ANY x402 tool call. Pass target URL + optional caller wallet, get back: live 402 price, recommended chain (via chain_picker logic), live facilitator health, caller reputation (via agent_id logic), and a green/yellow/red GO signal. Free tier — the universal preflight that lets agents decide before they sign. v2 (paid) will broker the actual settlement and proxy the response. (price: $0 USDC, tier: free)
