ScreenshotMAX with Java

Use Java's built-in HTTP client (java.net.http) to make signed or direct API calls.

Basic GET Screenshot

import java.io.*;
import java.net.*;

public class Main {
    public static void main(String[] args) throws Exception {
        String accessKey = "YOUR_ACCESS_KEY";
        String api = "https://api.screenshotmax.com/v1/screenshot";
        String params = String.format("access_key=%s&url=%s&format=png",
            accessKey,
            URLEncoder.encode("https://example.com", "UTF-8"));

        URL url = new URL(api + "?" + params);
        InputStream in = url.openStream();
        Files.copy(in, Path.of("screenshot.png"), StandardCopyOption.REPLACE_EXISTING);
        in.close();
        System.out.println("Image saved to screenshot.png");
    }
}

HMAC-Signed GET Screenshot

import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import java.io.InputStream;
import java.net.URI;
import java.net.URLEncoder;
import java.net.http.*;
import java.nio.charset.StandardCharsets;
import java.nio.file.Files;
import java.nio.file.Path;

public class ScreenshotMAX {
    public static void main(String[] args) throws Exception {
        String accessKey = "YOUR_ACCESS_KEY";
        String secretKey = "YOUR_SECRET_KEY";
        String api = "https://api.screenshotmax.com/v1/screenshot";

        String urlParam = URLEncoder.encode("https://example.com", "UTF-8");
        String format = "png";
        String query = "url=" + urlParam + "&format=" + format + "&access_key=" + accessKey;

        String signature = sign(secretKey, query);

        String finalURL = api + "?" + query + "&signature=" + signature;

        HttpRequest request = HttpRequest.newBuilder()
            .uri(URI.create(finalURL))
            .GET()
            .build();

        HttpClient client = HttpClient.newHttpClient();
        HttpResponse<InputStream> response = client.send(request, HttpResponse.BodyHandlers.ofInputStream());

        Files.copy(response.body(), Path.of("screenshot.png"));
        System.out.println("Screenshot saved to screenshot.png");
    }

    private static String sign(String key, String message) throws Exception {
        Mac hmac = Mac.getInstance("HmacSHA256");
        hmac.init(new SecretKeySpec(key.getBytes(StandardCharsets.UTF_8), "HmacSHA256"));
        byte[] hash = hmac.doFinal(message.getBytes(StandardCharsets.UTF_8));

        StringBuilder hex = new StringBuilder();
        for (byte b : hash) {
            hex.append(String.format("%02x", b));
        }
        return hex.toString();
    }
}
