How to get custom or filtered endpoints in WordPress API?

Question

I am using WordPress API to show posts. How can I get custom or filtered endpoints in WordPress API? I want only the following items:

• Post title
• Post content
• Post Date
• Post categories
• Post featured image
• Author name, bio and image

Everything else in the API should be omitted or create a new API URL. Is there any plugin I can use to do so?

I am not very good in PHP.

Here is an example of how to use Javascript to read posts from the WordPress API.

    //Pegasus = Theme name
$.getJSON('https://visionquestdevelopment.com/wp-json/wp/v2/posts', function(data){

  //foreach post
  for (i = 0; i < data.length; i++) {
    //console.log(data[i]);
    var output = '';
    var dateT;
    var dateArr = [];  

    //skip one of the posts with 404s on images 
    if( '1555'== data[i].id ) { continue; }

    //format date
    var dateTime = PegasusDateTime( data[i].date );
    dateArr = dateTime.toString().split(' ');
    //["Day of Week", "Month", "Day", "Year", "Time", "TimeZone"]
    var newTime = dateArr[1] + " " + dateArr[2] + ", " + dateArr[3]; 

    output += "Author " + data[i].author+"<br>";
    output += "Categories: " + data[i].categories+"<br>";
    output += data[i].content.rendered;
    output += "Date: " + newTime+"<br>";
    output += data[i].excerpt.rendered;
    output += "Attached Image ID: " + data[i].featured_media+"<br>";
    output += "Post Format: " + data[i].format+"<br>";
   //output += "GUID: " + data[i].guid+"<br>";
    output += "Post ID: " + data[i].id+"<br>";
    output += "Post URL: " + data[i].link+"<br>";
    output += "Custom Meta: " + data[i].meta+"<br>";
    output += "Slug: " + data[i].slug+"<br>";
    output += "Status: " + data[i].status+"<br>";
    output += "Tag IDs: " + data[i].tags+"<br>";

    $(".posts").append('<li class="item">' + output + '</li>');
  }


});

function PegasusDateTime(timeStr) {
    //eg:-timeStr=18-03-2013 12:53:00
    var tmstr = timeStr.toString().split(' '); //'21-01-2013 PM 3:20:24'
    var dt = tmstr[0].split('/'); //
    var str = dt[2] + "/" + dt[1] + "/" + dt[0] + " " + tmstr[1]; //+ " " + tmstr[1]//'2013/01/20 3:20:24 pm'
    //try to create the timestamp and set time variable to valid time
    var time = new Date(str);
    if (time == "Invalid Date") {
        time = new Date(timeStr);
    }

    return time;
}

Just modify the JS to include only the information you want.
