How can I use VirusTotal API in Delphi

To use the VirusTotal API in Delphi, you will need to perform the following steps:

Obtain an API key from VirusTotal. You can do this by signing up for a free account at https://www.virustotal.com/gui/join-us.
Install the Delphi REST Client Library, which is a framework for consuming RESTful web services in Delphi. You can find more information about this library and download the latest version from https://github.com/danieleteti/delphirestlib.
Use the Delphi REST Client Library to make HTTP requests to the VirusTotal API. You can use the TRESTClient and TRESTRequest components to do this.

Here is an example of how you can use the VirusTotal API to scan a file for viruses in Delphi:

uses
  REST.Client, REST.Types, REST.Authenticator.Basic;

procedure ScanFile(const FileName: string; const APIKey: string);
var
  RESTClient: TRESTClient;
  RESTRequest: TRESTRequest;
  RESTResponse: TRESTResponse;
begin
  RESTClient := TRESTClient.Create(‘https://www.virustotal.com/api/v3/’);
  try
    RESTRequest := TRESTRequest.Create(RESTClient);
    try
      RESTRequest.Method := rmPOST;
      RESTRequest.Resource := ‘files’;
      RESTRequest.Params.AddItem(‘apikey’, APIKey, pkQUERY);
      RESTRequest.AddBody(TFile.Create(FileName), ‘application/octet-stream’, FileName);

      RESTResponse := TRESTResponse.Create(RESTClient);
      try
        RESTRequest.Execute;
        if RESTResponse.StatusCode = 200 then
        begin
          // The file has been successfully scanned. You can now process the response data.
        end
        else
        begin
          // An error occurred while scanning the file. You can check the response data for more information.
        end;
      finally
        RESTResponse.Free;
      end;
    finally
      RESTRequest.Free;
    end;
  finally
    RESTClient.Free;
  end;
end;

uses

REST.Client, REST.Types, REST.Authenticator.Basic;

procedure ScanFile(const FileName: string; const APIKey: string);

var

RESTClient: TRESTClient;

RESTRequest: TRESTRequest;

RESTResponse: TRESTResponse;

begin

RESTClient := TRESTClient.Create(‘https://www.virustotal.com/api/v3/’);

try

RESTRequest := TRESTRequest.Create(RESTClient);

try

RESTRequest.Method := rmPOST;

RESTRequest.Resource := ‘files’;

RESTRequest.Params.AddItem(‘apikey’, APIKey, pkQUERY);

RESTRequest.AddBody(TFile.Create(FileName), ‘application/octet-stream’, FileName);

RESTResponse := TRESTResponse.Create(RESTClient);

try

RESTRequest.Execute;

if RESTResponse.StatusCode = 200 then

begin

// The file has been successfully scanned. You can now process the response data.

end

else

begin

// An error occurred while scanning the file. You can check the response data for more information.

end;

finally

RESTResponse.Free;

end;

finally

RESTRequest.Free;

end;

finally

RESTClient.Free;

end;

In this example, the ScanFile function takes the name of the file to scan and the VirusTotal API key as input, and makes an HTTP POST request to the files resource of the VirusTotal API to submit the file for scanning. The response data will contain information about the scan results, including any viruses that were detected. You can use the StatusCode property of the TRESTResponse object to check if the request was successful, and process the response data as needed.
