How would I make my combat script loot items above a certain price? 

I'm assuming you need to connect it to an external site that has the price of items or maybe directly connect it to the GE but I've searched the API and have failed to find something like this.

API

package me.Sinatra.Machine.Data;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URL;

public class GrandExchangeAPI
{
  private static final String BASE = "https://api.rsbuddy.com/grandExchange?a=guidePrice&i=";
  
  public int getOverallPrice(int itemID)
    throws IOException
  {
    return parse(itemID, "overall");
  }
  
  public int getBuyingPrice(int itemID)
    throws IOException
  {
    return parse(itemID, "buying");
  }
  
  public int getSellingPrice(int itemID)
    throws IOException
  {
    return parse(itemID, "selling");
  }
  
  private int parse(int itemID, String choice)
    throws IOException
  {
    URL url = new URL("https://api.rsbuddy.com/grandExchange?a=guidePrice&i=" + itemID);
    BufferedReader file = new BufferedReader(new InputStreamReader(url.openStream()));
    
    String price = null;
    String line;
    while ((line = file.readLine()) != null)
    {
      if (line.contains("{")) {
        price = line.trim();
      }
    }
    if (choice.equals("buying")) {
      price = price.substring(price.indexOf(",") + 10, nthOccurrence(price, ',', 1)).trim();
    } else if (choice.equals("selling")) {
      price = price.substring(nthOccurrence(price, ',', 2) + 11, price.indexOf("sellingQuantity") - 2).trim();
    } else {
      price = price.substring(price.indexOf(":") + 1, price.indexOf(",")).trim();
    }
    file.close();
    return Integer.parseInt(price);
  }
  
  private int nthOccurrence(String str, char c, int n)
  {
    int pos = str.indexOf(c, 0);
    while ((n-- > 0) && (pos != -1)) {
      pos = str.indexOf(c, pos + 1);
    }
    return pos;
  }
}

Usage

//in some class
private GrandExchangeAPI grandExchange;



//loot usage
this.grandExchange = new GrandExchangeAPI();

if conditions for loot
int worth = this.grandExchange.getSellingPrice(loot.getId());
if worth condition
     take

//Simple layout..clean it up and try to use it yourself.
//hope I managed to give insight
