        // Using a custom java.net.http.HttpClient instance
        client = new GeocodioClient(HttpClient.newBuilder().build(), "YOUR_GEOCODIO_API_KEY");

        // Error handling
        try {
            client.geocodeAsync("").get();
        } catch (ExecutionException e) {
            if (e.getCause() instanceof GeocodioStatusCodeException statusCodeException) {
                System.out.println(statusCodeException.statusCode());
                System.out.println(statusCodeException.responseBody());
            }
        }
    }
}

TODOs

• Add support for more forms of batch geocoding
• Add batch reverse geocoding
• Add non-async variants for all methods
