Is there any API for getting App Token & DBIDS w.r.t to table name?

> I pass table name as the parameter and I get the DBID.

Like this:

var name = "250 Bottles of Beer on the Form";

$.get("main?act=API_GrantedDBs")
  .then(function(xml) {
    var dbid = $("dbname", xml).filter(function() {
      return $(this).text() === name;
    }).next("dbid").text();
    console.log(dbid);
  })

//output
