Through OpenApi, which https://vk.com/js/api/openapi.js?159is  no way . GET method is registered there and is not configured. For cross-domain requests, the response is loaded via JSONP by including the script in the body of the document, where all request parameters go in its address with the same GET parameters. See the source of the above script, line 554 method makeRequest()and line 605 method attachScript()
From the server (Node.js?) it should not be a problem to POST the request to

https://api.vk.com/method/METHOD_NAME?PARAMETERS&access_token=ACCESS_TOKEN&v=V

as described in the documentation . True, when you call wall.post(), a confirmation window opens and everything is designed for the user's browser. How did you complete requests before and not encounter a captcha or confirmation window requirement?
