📚 How it works

• GET / — serves the UI.
• GET /api/proxies?cc=US — pulls a plaintext IP:port list for the given country code from a GitHub repo and parses it into JSON.
• GET /api/ping?ip=&port= — opens a raw socket with connect(), races it against a 2s timeout.

⚙️ Deploy

• Create a Cloudflare account.
• Navigate to Workers & Pages > Create > Create Worker.
• Deploy the worker by clicking Deploy.
• Edit the code by clicking Edit Code.
• Upload worker.js into Cloudflare.
• Finally, Deploy.
