Here is one example that you can invoke right from the developer console. This creates a traceflag on an User.

I have an example with 1 hard-coded value. If I do this outside the Apex environment, I can query that value as well. The hardcoded value is for DebugLevel.

I hope this helps.

String userToTrace = System.UserInfo.getUserId();
String endPoint = URL.getSalesforceBaseUrl().toExternalForm()+'/services/data/v36.0/tooling/sobjects/TraceFlag/';

HttpRequest req; 
HttpResponse res; 
Http h; 

req = new HttpRequest(); 
req.setHeader('Authorization', 'Bearer ' + UserInfo.getSessionID()); 
req.setHeader('Content-Type', 'application/json'); 
req.setBody('{"TracedEntityId":"' + userToTrace + '","LogType":"USER_DEBUG","DebugLevelId":"7dl700000008ONeAAM"}'); 
h = new Http(); 
res = h.send(req); 

One more thing, I had to white-list my salesforce domain url in the Remote Site settings. There is also another parameter that the traceflag payload can accept. That is expiration date. You may want to set an Expiration date when you do this.
