HttpClient client = HttpClient.newHttpClient();
// Build multipart form data with file + parameter
String boundary = "----Boundary" + System.currentTimeMillis();
byte[] fileBytes = Files.readAllBytes(Path.of("input.pdf"));

// See cURL example above for the equivalent command.
// For Java multipart uploads, consider using Apache HttpClient
// or Spring WebClient for simpler multipart handling.

// Example with Apache HttpClient:
// HttpEntity entity = MultipartEntityBuilder.create()
//     .addBinaryBody("file", fileBytes)
//     .addTextBody("keywords", "SSN,password,secret")
//     .build();
