list_x402_endpointsprobe_x402_endpointexecute_x402_endpoint (safe-by-default — probes first)send_inbox_message (use this instead of execute_x402_endpoint for inbox)scaffold_x402_endpoint and scaffold_x402_ai_endpointAlways probe before executing paid endpoints. Never call execute_x402_endpoint with autoApprove: true without checking cost first.
