Create a free Cloudflare account → Workers & Pages → Create Worker → replace the default code with the script below → Deploy. Copy the deployed *.workers.dev URL into the Proxy URL field above. This same worker also serves the Market Flipper page.

It forwards path-style requests (worker.dev/https://…, the same convention the Flipper uses), injects a real User-Agent, passes your Authorization: Bearer token through to GGG (OAuth mode) or turns an X-Poesessid header into a real Cookie (POESESSID mode — browsers won't let page JS set that header directly), forwards POSTs (for the OAuth token exchange), adds permissive CORS, and exposes the rate-limit headers so this page can pace itself.

This is the same method the original WealthyExile used, from before GGG's OAuth API existed. It reads your stash via your Path of Exile session cookie instead of a registered OAuth client — useful right now since GGG has paused new OAuth application registrations.

1. Log into pathofexile.com in this browser.
2. Open DevTools (F12) → Application (Chrome) or Storage (Firefox) tab → Cookies → https://www.pathofexile.com → copy the value of POESESSID.
3. Enter your account name (the one shown top-right on the site, e.g. YourName#1234) and paste the cookie value below, then click Use.

The Connect button runs GGG's official Authorization Code + PKCE flow (scopes account:profile account:stashes). It needs a registered OAuth client:

1. Register a public client at pathofexile.com → My Account → Applications (personal use is fine).
2. Set its redirect URI to exactly the value below (this page's own address — it auto-updates once the page is hosted).
3. Paste the issued Client ID here. Done — the button handles the rest, including token refresh.

Local-file fallback: OAuth redirects can't land on a file:// page, so when running unhosted you can still paste a manually-minted access token:

Docs: GGG OAuth reference.

OAuth's redirect handshake needs this page to live at a real https URL. Any free static host works — two easy options:

1. Cloudflare Pages (same account as your worker): dashboard → Workers & Pages → Create → Pages → Upload assets → drag this index.html in → Deploy. You get https://yourname.pages.dev.
2. GitHub Pages: push this file to a repo → Settings → Pages → deploy from branch. You get https://you.github.io/repo/.

Then open the hosted URL, check the Redirect URI box above (it shows the hosted address automatically), register it with your GGG OAuth client, paste the Client ID, and hit 🔗 Connect. Re-upload the file whenever it's updated — everything else (snapshots, settings) lives in your browser.

The Flipper, Build planner and Guide pages work identically when hosted — one file, one URL, no build step.
