MaxMind IPv4 Geolocation Lookup

See more Geolocation Examples

Demonstrates how to lookup Geolocation data for an IPv4 address using the MaxMind GeoIP2 Precision Web Service. Zig

const std = @import("std");

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    defer http.deinit();

    http.setLogin("MAXMIND_ACCOUNT_ID");
    http.setPassword("MAXMIND_LICENSE_KEY");
    http.setAccept("application/json");

    // Lookup an IPv4 address: 149.250.207.170  (this was a randomly chosen address)
    const json_str = http.quickGetStr(alloc, "https://geoip.maxmind.com/geoip/v2.1/country/149.250.207.170") catch {
