Web Risk API C++ Client Library

An idiomatic C++ client library for Web Risk, a service to detect malicious URLs on your website and in client applications.

While this library is GA, please note Google Cloud C++ client libraries do not follow Semantic Versioning.


The following shows the code that you'll run in the google/cloud/webrisk/quickstart/ directory, which should give you a taste of the Web Risk API C++ client library API.

#include "google/cloud/webrisk/v1/web_risk_client.h"
#include <iostream>

int main(int argc, char* argv[]) try {
  if (argc > 2) {
    std::cerr << "Usage: " << argv[0]
              << " [uri (default https://www.google.com)]\n";
    return 1;

  namespace webrisk = ::google::cloud::webrisk_v1;
  auto client =

  auto const uri = std::string{argc == 2 ? argv[1] : "https://www.google.com/"};
  auto const threat_types = {google::cloud::webrisk::v1::MALWARE,
  auto response = client.SearchUris("https://www.google.com/", threat_types);
  if (!response) throw std::move(response).status();
  std::cout << response->DebugString() << "\n";

  return 0;
} catch (google::cloud::Status const& status) {
  std::cerr << "google::cloud::Status thrown: " << status << "\n";
  return 1;
