Example usage of some key Draft Kings API endpoints to obtain players and salaries for a given sport's slate.

DraftKingsApi.js

const got = require('got');
const util = require('util');


(async () => {
    try {
        //Get the contests
        const contestsResponse = await got('https://www.draftkings.com/lobby/getcontests?sport=LOL');
        const contestsJson = JSON.parse(contestsResponse.body);

        //Loop through all contests and build a list of the unique draft groups
        let groupIdList = [];
        contestsJson['Contests'].forEach(contest => {
            if (!groupIdList.includes(contest['dg'])) {
                groupIdList.push(contest['dg'])
            }
        });

        //For each draft group, grab the draftables by replacing the parameter in the URL with the correct group Id
        for (const groupId of groupIdList) {
            console.log('Players for GroupId:')
            console.log(groupId);

            const draftableplayersJson = JSON.parse(draftablePlayersResponse.body);

            //Nice! Now we have the players so let's just console.log them as a simple example
