Call this tool only when the user wants the action performed, not merely researched or compared. Supply a specific natural-language query describing the desired action and an arguments object containing the selected provider tool inputs when known. Euvra independently re-plans the route and does not accept caller-selected provider IDs, endpoints, or tool names. Execution may return NO_ROUTE, AUTH_REQUIRED, or BLOCKED if no eligible live tool is available. Paid execution requires an x402 payment of 0.01 USDC on the configured network; a client without payment support may receive payment requirements instead of an executed result. Do not claim the action succeeded until the response confirms success.",
