C++ AI detector quickstart

Send at least 150 characters for a more reliable signal. The response score ranges from 0 (more likely human-written) to 1 (more likely AI-generated); use it as evidence, not proof.

No language-specific SDK is required. The example uses a standard or commonly used HTTP client to call Sapling's JSON API.

C++ /api/v1/aidetect

C++ has no standard HTTP client, so this example uses libcurl.

#include <curl/curl.h>
#include <cstdlib>
#include <iostream>
#include <stdexcept>
#include <string>

int main() {
  const char* key = std::getenv("SAPLING_API_KEY");
  if (key == nullptr) {
    throw std::runtime_error("Set SAPLING_API_KEY first.");
  }

  CURL* curl = curl_easy_init();
  if (curl == nullptr) {
    throw std::runtime_error("Could not initialize libcurl.");
  }

  std::string authorization = std::string("Authorization: Bearer ") + key;
  curl_slist* headers = nullptr;
  headers = curl_slist_append(headers, authorization.c_str());
  headers = curl_slist_append(headers, "Content-Type: application/json");

  const std::string payload =
      R"({"text":"I am an artificial intelligence system designed to help people solve complex problems. My capabilities include natural language processing, machine learning, and predictive analytics.","sent_scores":true})";

  curl_easy_setopt(curl, CURLOPT_URL, "https://api.sapling.ai/api/v1/aidetect");
  curl_easy_setopt(curl, CURLOPT_POST, 1L);
  curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
  curl_easy_setopt(curl, CURLOPT_POSTFIELDS, payload.c_str());

  const CURLcode result = curl_easy_perform(curl);
  long status = 0;
  curl_easy_getinfo(curl, CURLINFO_RESPONSE_CODE, &status);

  curl_slist_free_all(headers);
  curl_easy_cleanup(curl);

  if (result != CURLE_OK || status < 200 || status >= 300) {
    std::cerr << "Request failed: " << curl_easy_strerror(result)
              << " (HTTP " << status << ")\n";
    return 1;
  }
  return 0;
}

Example response application/json

{
  "score": 0.9989,
  "sentence_scores": [
    {
      "score": 0.9764,
      "sentence": "I am an artificial intelligence system designed to help people solve complex problems."
    },
    {
      "score": 0.9812,
      "sentence": "My capabilities include natural language processing, machine learning, and predictive analytics."
    }
  ],
  "text": "I am an artificial intelligence system designed to help people solve complex problems. My capabilities include natural language processing, machine learning, and predictive analytics."
}

The overall score and sentence scores use different methods and may not match exactly. Choose thresholds based on the false-positive and false-negative costs of your use case.

About C++

C++ is an object-oriented programming language that provides a superset of features of C. It is a popular choice for large programming projects that require the performance characteristics of C but want code organized as classes. Cross-platform applications developed with the Qt framework typically are written in C++.
