Geo-redirect visitors by country

Route visitors to a regional site, language, or pricing page based on the country of their IP address.

1. Look up the visitor's IP from your server

Read the visitor's IP from the incoming request and ask the API for its country. Keep your key on the server.

// Node/Express
app.get("/", async (req, res) => {
  const ip = req.headers["x-forwarded-for"]?.split(",")[0] || req.socket.remoteAddress;
  const r  = await fetch(`https://ipquery.info/api?apiKey=YOUR_API_KEY&ip=??ip??`);
  const country = (await r.json())[0]?.country_iso_code;
  const map = { GB: "/uk", DE: "/de", US: "/us" };
  res.redirect(map[country] || "/us");
});

2. Read country_iso_code

The response is an array with one object per IP. Use country_iso_code (ISO 3166-1 alpha-2, e.g. GB) for routing; continent and is_eu_member are handy for coarser rules.

3. Cache to protect your quota

Cache the result per IP (or per /24) for a few hours so repeat visits don't spend additional requests. Bulk lookups cost one request per address, so single look-ups are best for per-visitor routing.
