https://developer-portal.driver-vehicle-licensing.api.gov.uk/apis/vehicle-enquiry-service/vehicle-enquiry-service-description.html#introduction

    button.onclick = function(){
        var reg = document.getElementById("symb").value;
    document.getElementById("databox").innerHTML = " ";
    
    var xhr = new XMLHttpRequest();
    var url = "url";
    xhr.open("POST", url, true);
    xhr.setRequestHeader("Content-Type", "application/json")
    xhr.setRequestHeader("user","my name");
    xhr.onreadystatechange = function () {
        if (xhr.readyState === 4 && xhr.status === 200) {
            var json = JSON.parse(xhr.responseText);
            console.log(json.email + ", " + json.password);
        }
   };
var data = JSON.stringify({"registrationNumber": "rf23mzv"});
xhr.send(data);

}

The link you posted specifies

Every client is issued an API Key which is passed into the request as a mandatory named header as follows:

name: x-api-key
value: {supplied API key}

Thus, you have to add this header to your request, and provide the API key that you have been given.

If you want to keep using XHR, add it like you add the Content-Type header:

xhr.setRequestHeader("x-api-key", "put-your-api-key-here");

IMO this is much easier with the fetch api instead of the classic XHR. It should let you replace all your snippet with something like this:

fetch('https://driver-vehicle-licensing.api.gov.uk/vehicle-enquiry/v1/vehicles', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'x-api-key': 'put-your-api-key-here',
  },
  body: JSON.stringify({registrationNumber: 'rf23mzv'}),
})
.then(res => res.json())
.then(console.log)
