Binance search API returns 403 when using with google scripts

I'm using the binance API to get the prices of usdt. The API works on postman but it doesn't work on google script.

function fetchCryptoPricesFromApi() {
  const data = {
    "page": 1,
    "rows": 10,
    "payTypes": [],
    "asset": "USDT",
    "tradeType": "SELL",
    "fiat": "LKR",
    "publisherType": null,
    "transAmount": "2600"
  }

  const payload = JSON.stringify(data)

  const options = {
    "method" : "POST",
    "contentType" : "application/json",
    "payload" : payload
  }

  let response;
  
  try {
    response = UrlFetchApp.fetch('https://p2p.binance.com/bapi/c2c/v2/friendly/c2c/adv/search', options);
  } catch (error) {
    console.log('Oops Error, ', error);
    return
  }

  const prices = JSON.parse(response)['data'];
  console.log(prices)
}

I get the following error when executing this,

Oops Error,  { [Exception: Request failed for https://p2p.binance.com returned code 403. Truncated server response: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<HTML><HEAD><META HTTP-EQUIV="Content-Type" ... (use muteHttpExceptions option to examine full response)] name: 'Exception' }

I tried waiting some time as well.

Solution

  • From your showing error message, I confirmed the status code 403. Ref In this case, it is considered that the site cannot be directly accessed from the Google side. I think that the reason for your issue is due to this.

    In this case, as a workaround, I would like to propose access to the URL without directly running the script with the script editor. When I tested this workaround, I confirmed that the value could be returned.

    In this workaround, the following flow is used.

    1. Put the custom function of =fetchCryptoPricesFromApi() to a cell.
    2. Retrieve the values from the API.
    3. Retrieve the values from the cell.
    4. Parse the value as JSON data.

    The sample script of this workaround is as follows.

    Sample script:

    In this workaround, I use Google Spreadsheet. So please create a new Google Spreadsheet and open the script editor of Google Spreadsheet. And, copy and paste the following script. And, run main() function with the script editor.

    function fetchCryptoPricesFromApi() {
  const data = {
    "page": 1,
    "rows": 10,
    "payTypes": [],
    "asset": "USDT",
    "tradeType": "SELL",
    "fiat": "LKR",
    "publisherType": null,
    "transAmount": "2600"
  }
  const payload = JSON.stringify(data)
  const options = {
    "method": "POST",
    "contentType": "application/json",
    "payload": payload
  }
  const response = UrlFetchApp.fetch('https://p2p.binance.com/bapi/c2c/v2/friendly/c2c/adv/search', options);
  return response.getContentText();
}

// Please run this function.
function main() {
  const sheet = SpreadsheetApp.getActiveSheet();
  const range = sheet.getRange("A1");
  range.setFormula("=fetchCryptoPricesFromApi()");
  SpreadsheetApp.flush();
  const value = range.getValue();
  range.clearContent();
  const prices = JSON.parse(value)['data'];
  console.log(prices)
}
