How to set the frequency of loaddata requests

Processing Coding Questions

Hi, I am still exploring this interesting code, but I met this problem today.

I tried to use API to get real-time wind data from a website, but the free plan only allows me to request data 500 times a day.

So I was wondering if there is any way to make my loadData() run every 3 minutes.

Thanks

float x;
float y;
float wd;
float ws;
float tw;
JSONObject json;
String q = "Hello,world";
String url = "https://api.weatherbit.io/v2.0/current?lat=78.13&lon=15.38&key="; 

void setup(){
  size(1920,1080);
  fill(0);
  x = width/2;
  y = 100;
  loadData();
    
}


void draw(){
  
  background(255);

  x += cos(radians(wd))*(ws);
  y += sin(radians(wd))*(ws);
  
  translate(x, y);
  rotate(radians(wd));
  
  textSize(ws*10);
  
  tw = textWidth(q);
  
  text(q, 0, 0, tw+1, 800);
  
  if (x < 0){
    x = width;
  }
  
  if (x > width){
    x = 0;
  }
  
  if (y > height){
    y = 0;
  }
  
  if (y < 0){
    y = height;
  }
} 


void loadData(){
  json = loadJSONObject(url);
  
  JSONArray weatherdata = json.getJSONArray("data");
  
  for (int i = 0; i < weatherdata.size(); i++){
  JSONObject data = weatherdata.getJSONObject(i);
  wd = data.getInt("wind_dir");
  ws = data.getFloat("wind_spd");
 }
}
