Hello,so i want to get an active price of an item,what i thought is take a price of osrs url example :

http://services.runescape.com/m=itemdb_oldschool/Green_dragonhide/viewitem?obj=1753

 

but thing is how do i make that? I mean script to pick up only the "price" thing?

thank you everyone for the answers

3 years ago but I believe nothings changed -> https://www.reddit.com/r/2007scape/comments/3g06rq/guide_using_the_old_school_ge_page_api/

Should be able to get it working with a bit of Googling on how to send the requests / parse JSON responses

Some code from a project I was working on. Should be enough to get you started.

ummm well,that reddit post is.. cant really say worthless,but what i think is:

you define url as a string

String url = "google.com";

then somehow get the text from the url,and thats it ?

package osbot_scripts.framework;

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

public class GEPrice {

	private static final String BASE = "https://api.rsbuddy.com/grandExchange?a=guidePrice&i=";

	/**
	 * Default Constructor
	 * 
	 */
	public GEPrice() {

	}

	/**
	 * Gets the overall price of an item.
	 * 
	 * @param itemID
	 * @return itemPrice
	 * @throws IOException
	 */
	public int getOverallPrice(final int itemID) throws IOException {
		return parse(itemID, "overall");
	}

	/**
	 * Gets the buying price of an item.
	 * 
	 * @param itemID
	 * @return itemPrice
	 * @throws IOException
	 */
	public int getBuyingPrice(final int itemID) throws IOException {
		return parse(itemID, "buying");
	}

	/**
	 * Gets the selling price of an item.
	 * 
	 * @param itemID
	 * @return itemPrice
	 * @throws IOException
	 */
	public int getSellingPrice(final int itemID) throws IOException {
		return parse(itemID, "selling");
	}

	/**
	 * Retrieves the price of an item.
	 * 
	 * @param itemID
	 * @return itemPrice
	 * @throws IOException
	 */
	private int parse(final int itemID, String choice) throws IOException {
		final URL url = new URL(BASE + itemID);
		BufferedReader file = new BufferedReader(new InputStreamReader(url.openStream()));
		String line;
		String price = null;
		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;
	}
}

From DoricsQuester, not sure who made it but seems pretty clean. To use it you can use the following:

GEPrice grandExchangePrices = new GEPrice();

int price = grandExchangePrices.getBuyingPrice(1028);

log(price);
