Execute code immediately and wait for results. Best for quick scripts and interactive use.

Request Parameters

Example (C++)

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

int main() {
  CURL *curl;
  CURLcode res;

  curl = curl_easy_init();
  if (curl) {
    struct curl_slist *headers = nullptr;
    headers = curl_slist_append(headers, "Content-Type: application/json");
    headers = curl_slist_append(headers, "Authorization: Bearer YOUR_API_KEY");

    std::string json = "{"
                       "\"language\": \"python\","
                       "\"code\": \"print('Hello from unsandbox!')\""
                       "}";

    curl_easy_setopt(curl, CURLOPT_URL, "https://api.unsandbox.com/execute");
    curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, json.c_str());

    res = curl_easy_perform(curl);

    if (res != CURLE_OK)
      std::cerr << "curl_easy_perform() failed: " << curl_easy_strerror(res)
                << std::endl;

    curl_slist_free_all(headers);
    curl_easy_cleanup(curl);
  }
  return 0;
}

Response (Success)

{
  "success": true,
  "stdout": "Hello from unsandbox!\n",
  "stderr": "",
  "error": null,
  "language": "python",
  "exit_code": 0
}

Response (Error)

{
  "success": false,
  "error": "Syntax error in code",

Possible Status Values

• pending - Job queued, waiting to execute
• running - Job currently executing
• completed - Job finished (check result field)
• timeout - Job exceeded TTL limit
• cancelled - Job was cancelled via DELETE

List all active (pending or running) jobs for your API key. Useful for monitoring multiple async executions.
