importJSON in Google Sheet reduce API connections? - google-apps-script

Question

I have made an other question here:
First question
It seems I'm calling to much the API.
My script calls 23 times the API in one go.
This is how my script looks like :
var ss = SpreadsheetApp.getActiveSheet();
//Creates a menu called Crypto.
function onOpen() {
var ui = SpreadsheetApp.getUi();
ui.createMenu('Crypto')
.addItem('Update Prices','updatePrices')
.addItem('Update Sheet','updateSheet')
.addToUi();
}
//Copy cells.
function copyCell() {
ss.getRange("D2:D13").copyTo(ss.getRange("E2"), {contentsOnly:true});
ss.getRange("B2:B13").copyTo(ss.getRange("G2"), {contentsOnly:true});
ss.getRange("M1").copyTo(ss.getRange("M2"), {contentsOnly:true});
ss.getRange("M5").copyTo(ss.getRange("M6"), {contentsOnly:true});
}
/**
* Imports JSON data to your spreadsheet Ex: IMPORTJSON("https://api.coinmarketcap.com/v2/ticker/1/?convert=EUR","data/quotes/EUR/price")
* #param url URL of your JSON data as string
* #param xpath simplified xpath as string
* #customfunction
*/
function IMPORTJSON(url,xpath){
try{
// /rates/EUR
var res = UrlFetchApp.fetch(url);
var content = res.getContentText();
var json = JSON.parse(content);
var patharray = xpath.split("/");
//Logger.log(patharray);
for(var i=0;i<patharray.length;i++){
json = json[patharray[i]];
}
//Logger.log(typeof(json));
if(typeof(json) === "undefined"){
return "Node Not Available";
} else if(typeof(json) === "object"){
var tempArr = [];
for(var obj in json){
tempArr.push([obj,json[obj]]);
}
return tempArr;
} else if(typeof(json) !== "object") {
return json;
}
}
catch(err){
return "Error getting data";
}
}

//Copy the formula's from row 19 to last filled cell in A and B.
var row = 19;
CopyFormulasDown.copyFormulasDown(ss, row);
}
The problem with V2 api of CMC is that the BTC price has to be checked with an other URL. I'm not a hero in array's. Sorry.
I'm thinking of pulling four times the ticker API and then find the right info
1. https://api.coinmarketcap.com/v2/ticker/?convert=EUR
2. https://api.coinmarketcap.com/v2/ticker/?convert=EUR&start=101
3. https://api.coinmarketcap.com/v2/ticker/?convert=EUR&start=201
4. https://api.coinmarketcap.com/v2/ticker/?convert=EUR&start=301
Because the api limits to 100 tickers I have to create 4. I'm using V2 of the IP and I'm using the ID to get the right currency. That is the number behind the ticker. I have to use 4 downloads because The highest rank of currency is 316.
What is the best way to optimize this script with out calling to much api's?

Answer 1

I have reduced my script. It now has 4 api calls. Sometimes still to much for coinmarketcap.
var ss = SpreadsheetApp.getActiveSheet();
//Creates a menu called Crypto.
function onOpen() {
var ui = SpreadsheetApp.getUi();
ui.createMenu('Crypto')
.addItem('Update Prices','updatePrices')
.addItem('Update Sheet','updateSheet')
.addToUi();
}
//Copy cells.
function copyCell() {
ss.getRange("D2:D13").copyTo(ss.getRange("E2"), {contentsOnly:true});
ss.getRange("B2:B13").copyTo(ss.getRange("G2"), {contentsOnly:true});
ss.getRange("M1").copyTo(ss.getRange("M2"), {contentsOnly:true});
ss.getRange("M5").copyTo(ss.getRange("M6"), {contentsOnly:true});
}
