Google Script - REST API public endpoints
Our REST API public endpoints are accessible via a simple HTTP request (just as a web page is requested via a web browser), so an API client to import market data into a Google Sheet can be implemented with just a few lines of Google Script code.


  1. 1
    Create a new Google Sheet or open an existing sheet
  2. 2
    Open the script editor via the Extensions -> Apps Script menu
  3. 3
    Delete the default code that is shown (Select All then Delete/Backspace, for example)
  4. 4
    Copy/Paste the Google Script API code (shown below) into the script editor
  5. 5
    Optional - Add any additional custom functions that you require (to call different endpoints or return different JSON fields, for example)
  6. 6
    Save the Google Script Code via the
    (Save project) icon


The KAPI_Public() function is responsible for creating the appropriate URL and making the HTTP request to the API. The KAPI_Public() function can be called directly by entering the following (or similar depending upon the endpoint and the parameters) within a Google Sheet cell:
  • =KAPI_Public("Ticker", "pair=xbtusd,etheur,ltcusd,xdgxbt")
  • =KAPI_Public("Spread", "pair=xbtusd")
  • =KAPI_Public("Depth", "pair=ethusd&count=5")
The KAPI_Public() function returns the original JSON response from the API, such as the following for the above Depth endpoint example:
  • {"error":[],"result":{"XETHZUSD":{"asks":[["231.74000","4.386",1583402326],["231.75000","27.337",1583402277],["231.76000","5.887",1583402311],["231.79000","36.280",1583402334],["231.80000","50.000",1583402299]],"bids":[["231.70000","18.534",1583402335],["231.67000","22.109",1583402335],["231.61000","7.930",1583402335],["231.60000","33.841",1583402335],["231.54000","115.017",1583402334]]}}}
In order to place the individual fields/values into separate cells within the Google Sheet, additional custom functions can be called to parse the JSON response, such as the example KAPI_Ticker() and KAPI_Depth() functions:
  • =KAPI_Depth("XDGUSD", "5")
which would display the results similar to the following, where the data would be accessible to any of the standard Google Sheets functions (SUM, AVERAGE, COUNT, etc.):

Google Script Code

function KAPI_Public(endpoint, parameters) {
  http_response = UrlFetchApp.fetch('https://api.kraken.com/0/public/' + endpoint + '?' + parameters)
  api_data = http_response.getContentText()
  return api_data

function KAPI_Ticker(currency_pairs) {
  api_data = JSON.parse(KAPI_Public("Ticker", "pair=" + currency_pairs))
  api_results = new Array
  for ( name in api_data['result'] ) {
    api_results.push([ name, api_data['result'][name]['a'][0], api_data['result'][name]['a'][2], api_data['result'][name]['b'][0], api_data['result'][name]['b'][2], api_data['result'][name]['c'][0], api_data['result'][name]['c'][1] ])
  return api_results

function KAPI_Depth(currency_pair, depth) {
  api_data = JSON.parse(KAPI_Public("Depth", "pair=" + currency_pair + "&count=" + depth))
  api_results = new Array
  for ( count = 0; count < parseInt(depth); count++ ) {
    api_results.push([ api_data['result'][currency_pair]['bids'][count][0], api_data['result'][currency_pair]['bids'][count][1], api_data['result'][currency_pair]['asks'][count][0], api_data['result'][currency_pair]['asks'][count][1] ])
  return api_results
