How to choose which API "DEX2 CreateRData" or "EikonDesktopDataAPI CreateAdxRtList"

@SAKAMOTO

Is this the data you are looking for ?

I use "Data Item Browser" on Eikon to search for the field name. (see bottom right of the window)

I tested the App Studio WEB SDK with this request:

        var request = {
           "instruments":"JP03420067=",
           "fields":"TR.FIMaturityDate"
         };

         JET.Data("datagrid").then(function (service) {
           service.request(request).then(function (result) {
             console.log(result);
           }, function (err) { console.log(err); });
         });

And this is the result I received:

{"columnHeadersCount":0,"data":[["2026-03-20"]],"rowHeadersCount":0,"totalColumnsCount":1,"totalRowsCount":1}
