GeoIP Auto-Resolution

When using proxies in different countries, your browser fingerprint should match the proxy's location. GeoIP auto-resolution handles this automatically.

How It Works

const session = await strike({
  proxy: "http://za-proxy.example.com:8080",
  geoip: true,
});

When geoip: true:

1. cykani queries the proxy IP's geolocation via a public IP API
2. Sets locale to the country's primary language (e.g., en-ZA for South Africa)
3. Sets timezone to the IP's timezone (e.g., Africa/Johannesburg)
4. Sets Accept-Language header to match (e.g., en-ZA,en;q=0.9)

What Gets Set

Why It Matters

Detection sites check for consistency between:

• Your IP address location
• Your timezone
• Your locale
• Your Accept-Language header

A mismatch is a strong bot signal. For example, a South African IP with America/New_York timezone is suspicious.

// Good: Everything matches
const session = await strike({
  proxy: "http://za-proxy:8080",
  geoip: true,
});

// Bad: Mismatched
const session = await strike({
  proxy: "http://za-proxy:8080",
  locale: "en-US", // South African proxy, US locale
  timezone: "America/New_York",
});

Without GeoIP

If you prefer manual control:

const session = await strike({
  proxy: "http://proxy.example.com:8080",
  locale: "de-DE",
  timezone: "Europe/Berlin",
});

GeoIP is disabled by default — you must explicitly set geoip: true.
