# QuantScapers > QuantScapers is a free set of OSRS (Old School RuneScape) tools for reading > the Grand Exchange. It never trades for the user. It shows numbers for the > player to act on manually. ## Market - [OSRS Grand Exchange market](https://quantscapers.com/market) is a live OSRS Grand Exchange overview with a filterable item table, top gainers/losers ("movers"), and stored price history charts. It is free and requires no account. - [Market table](https://quantscapers.com/market/table) lets you search a sortable OSRS Grand Exchange item table by price, ROI, volume, and quote age. - [Market heatmap](https://quantscapers.com/market/heatmap) shows 100 tracked megarare and PvM items, sized by price and colored by 24-hour or 7-day change, with average change across non-hatched items and CSV and PNG exports. - [Sector rotation](https://quantscapers.com/market/rotation) charts OSRS Grand Exchange sectors against the equal-weight QS Liquid 200 benchmark, with quadrants and 4-week tails. - [OSRS market this week](https://quantscapers.com/market/this-week) shows how tracked item prices changed over seven days, gives each item equal weight in the median, and links to past GE Desk reports. ## Items - [Items A–Z](https://quantscapers.com/market/items) lets visitors browse OSRS Grand Exchange items alphabetically, with links to pages for currently priced items and the featured pilot items. **Item price history citations** start on item pages such as https://quantscapers.com/market/item/berserker-ring. When the page can show historical facts, its price-history section links to a dated permalink at `https://quantscapers.com/market/item//YYYY-MM-DD` and a CSV at `https://quantscapers.com/market/item//history.csv`. The dated page summarizes available hourly samples through that date; its “As of” line gives the last sample date. Dated pages are noindexed and canonicalize to the base item page. The noindexed CSV contains UTC timestamps, average high and low prices in GP, and sampled volume, with source, date, units, and price convention in its comment header. ## Indices - [Market indices](https://quantscapers.com/market/indices) lists themed item baskets (e.g. Melee/Ranged/Magic gear tiers, PvP loadouts, Teleports, High-Level Food, High-Level Potions), each trackable at [an index page](https://quantscapers.com/market/index/) with live basket performance. - [Raids 4 items to watch](https://quantscapers.com/market/raids-4-items-to-watch) covers hourly prices and player discussion of five Fractured Archive uniques before and after the raid opened. ## Tools - [Tools](https://quantscapers.com/market/tools) links to Best items to flip, the Item set calculator, the High alchemy scanner, and the Death's Coffer scanner. - [Best items to flip](https://quantscapers.com/market/best-items-to-flip) compares OSRS flip candidates by after-tax margin and buy limit across four bankroll tiers, using live GE quotes and 24-hour volume. - [Item set calculator](https://quantscapers.com/market/sets) compares packing and breaking OSRS item sets using after-tax prices, buy limits, recent volume, and stored history. - [High alchemy scanner](https://quantscapers.com/market/alch) compares OSRS high alchemy value with live buy prices and nature rune cost to find positive profit per cast. - [Death's Coffer scanner](https://quantscapers.com/market/coffer) compares GE prices with Death's Coffer credit, set at 105% of the official GE guide price, and shows buy limits and volume. QuantScapers refreshes its item data hourly with guide prices from OSRS Wiki bulk data. The Wiki updates guide prices about every three hours. A missing or stale guide price leaves Coffer value unavailable. ## Guides - [Guides](https://quantscapers.com/resources/) covers OSRS Grand Exchange trading strategy, market mechanics, flipping, and update speculation. - [GE Desk](https://quantscapers.com/resources/ge-desk/) lists weekly OSRS Grand Exchange market briefs in date order. ## Plugin - [Plugin](https://quantscapers.com/plugin) is a RuneLite plugin available in the RuneLite Plugin Hub. It turns Grand Exchange price data into a BUY / DECENT / RISKY / AVOID verdict per item, with an exact order ticket (quantity, buy price, sell price, after-tax profit). Install it from the Plugin Hub inside the RuneLite client. It reads game data. It never plays for the user. ## Data source All price data comes from the public OSRS Wiki Real-time Prices API (https://prices.runescape.wiki/osrs/). QuantScapers does not scrape or reverse-engineer the data. ## Key facts - Both tools are free with no account required. - Neither tool automates trades or touches the Grand Exchange interface. - Grand Exchange tax is 2%, capped at 5,000,000 GP, and waived under 50 GP. QuantScapers applies this tax rule when computing profit. - Not affiliated with Jagex Ltd. ## Full FAQ See https://quantscapers.com/#faq for the complete, current FAQ.
