PoE Price Check

Price checking for Path of Exile when you play through a cloud gaming service such as Boosteroid — where every other price-check tool stops working.

Why this exists

Awakened PoE Trade and everything like it reads your clipboard. When the game runs in a data centre and you sit in front of a browser, that clipboard is not yours: Ctrl+C fills the clipboard there. Boosteroid synchronises the clipboard one way only — local to cloud — so nothing comes back.

How it gets around that

The item text is pushed out of the cloud session through a Google Doc that acts as a bridge:

game (cloud)  --Ctrl+C-->        cloud clipboard
              --F7-->            Steam overlay browser, bridge doc open
              --Ctrl+A, Ctrl+V-->  Google Doc
your PC       --HTTP GET-->      doc text -> parse -> pathofexile.com/trade

One keypress in game, a result window on your machine a moment later.

Features

• Interactive mod panel — untick what does not matter, search again in place
• Tier ranges read from the item, minimum only, so better rolls still show up
• Pseudo totals: total elemental resistance, total life, attributes
• Divine/chaos conversion from live rates, median based, outliers dropped
• Item level and link sliders, hidden mods, craftable-affix detection
• Trade status set to instant buyout
• Interface in English, Polish, German, Spanish, Portuguese and Russian, picked automatically from the Windows locale

Install

Download the archive from poepricecheck.eu, unpack it, run poe-price-check.exe. A setup wizard walks you through the bridge document and the Steam overlay settings.

Windows will say the publisher is unknown — the build is not code-signed, because a certificate costs several hundred euros a year and this is free. Choose More info → Run anyway. The program also installs a global keyboard hook, which is the only way to catch a shortcut while the game has focus; some antivirus software flags that heuristically. Build it yourself if you would rather be sure what you are running.

Build from source

Python 3.11+.

pip install -r requirements.txt pyinstaller
python -m PyInstaller --noconfirm poe-price-check.spec

The result is a single dist/poe-price-check.exe with no dependencies.

python check_i18n.py   # translation coverage, no hardcoded interface strings
python smoke_test.py   # live round trip against the trade API

Layout

Path	What it is
main.py	entry point, hotkeys, wiring
item_parser.py	parses the clipboard text the game produces
trade_api.py	maps mods to stat ids, builds and runs trade queries
bridge.py	the cloud-session clipboard bridge
overlay.py, status_window.py, setup_window.py	Tk interface
i18n.py	translations, six languages
web/	the website, its backend and the stats panel

The website runs on Cloudflare Pages Functions with a D1 database — see web/DEPLOY.md.

Code comments are in Polish; everything user-facing is translated.

Privacy

The app sends an anonymous usage counter: version, operating system, language, league, number of price checks. Never items, prices, account details or your bridge document id. The install identifier is random and tied to nothing. Set "telemetry": false in config.json to switch it off.

The website counts visits without cookies and without storing IP addresses.

About the trade API

This tool calls the same website endpoints that pathofexile.com/trade uses in your browser. Those are not part of GGG's documented developer API, and GGG's developer documentation states that using endpoints outside that documentation is against section 7i of their Terms of Use. Applications for documented API access are closed at the time of writing. The whole family of community price checkers works this way and has done for years, but go in knowing that.

The client throttles itself from the X-Rate-Limit-* headers and honours Retry-After. Do not spam the hotkey.

Releases

Every release is built by GitHub Actions from a tagged commit — see .github/workflows/build.yml. Nothing built on a personal machine is published. Each release publishes the SHA-256 of the executable so you can check what you downloaded.

How releases are approved and what would be signed: SIGNING-POLICY.md.
