:warning: Do not spam requests to the APIs: The services may time you out!

Trade Volume Data (OSRS's grand exchange graphs)

(Not available on the official OSRS API) This will return trade volume data from the official website.

const data = await OSRS.getTradeVolume(4151);
console.log(data);

Output:

  // ...
  {
    tradeVolume: 1616,
    date: 2020-09-19T23:00:00.000Z,
    dateString: '9/20/2020',
    priceAverage: 2670124,
    priceDaily: 2659245
  },
  {

    priceAverage: 2669650,
    priceDaily: 2678354
  },
  //... 80 more items

Bare bones OSRS API that is publicly available.

const itemData = await OSRS.getFromOfficialAPI(OSRS.ITEMS_LIST.Abyssal_whip);
console.log(itemData);

OSRS Wiki API

Get long term trading data from the wiki.

const tradeData = await OSRS.getFromWiki(4151);
console.log(tradeData); // tradeVolume undefined as tracking began in 2018
console.log(tradeData[tradeData.length - 10]); // this should have some tradeVolume data

Output:

// ...
  { // Old data
    date: 1430006400000,
    dateString: '04/26/2015',
    priceDaily: 2488963,
    tradeVolume: undefined
  },
  {
    date: 1430092800000,
    dateString: '04/27/2015',
    priceDaily: 2571803,
    tradeVolume: undefined

CORS

Some of the endpoints may require a cors proxy, such as cors anywhere. To supply this to, simply pass it in as a parameter.

const tradeData = await API.getTradeVolume(
  4151,
  'https://cors-anywhere.herokuapp.com/',
);

This should now work in the browser.
