Can anyone help? I’m trying to send a POST request to: https://api.vapi.dev/v1/tools/call-response …to respond to a tool_call_id, as documented in your tools API flow. But I’m consistently getting: getaddrinfo ENOTFOUND api.vapi.dev or Service not reachable This happens from Postman, curl, and Make.com — across multiple networks and devices. Is this endpoint live? And if not, what is the correct URL I should use to send tool responses?
