Keylance provides a simple REST API to validate and manage your license keys in real-time. This API works with any engine, framework, or language that supports HTTP requests. You don’t need to use our SDK — just make a GET request to verify a key and get back structured JSON.

To validate a license key, make a GET request to:

https://aukkeproduction.fr/Keylance_Api/VerifKey.php?key=API_KEY&project=PROJECT_KEY

🧾 Parameters:

• key: Your user’s API key
• project: The project’s unique license key

📄 Example (cURL):

curl "https://aukkeproduction.fr/Keylance_Api/VerifKey.php?key=abc123&project=def456"

The response will look like:

{
  "success": true,
  "is_protected": true,
  "active": true,
  "expiration_date": "2025-12-31"
}

🧩 Field Details:

• success: Whether the request was valid
• is_protected: If the project is still under Keylance protection
• active: Whether the license is currently active
• expiration_date: The fallback expiration date (offline mode)

• Block access if a client hasn’t paid (remotely disable the license)
• Enable offline expiration if no internet connection
• Show a warning screen inside your software/tool
• Track usage through our automatic connection logs

Unreal Engine (via HTTP request):

FHttpModule::Get().CreateRequest()->SetURL("...VerifKey.php?...");

PHP:

$response = file_get_contents("https://aukkeproduction.fr/Keylance_Api/VerifKey.php?key=XXX&project=YYY");
$data = json_decode($response, true);
if ($data["success"] && $data["active"]) { /* OK */ }
        

JavaScript:

fetch("https://aukkeproduction.fr/Keylance_Api/VerifKey.php?key=XXX&project=YYY")
.then(res => res.json())
.then(data => {
  if (data.success && data.active) {
    console.log("Access granted");
  }
});
        

• If success = false → the key is wrong or not found
• If active = false → the license was disabled
• If expiration_date has passed → fallback mode triggers
• If the server is unreachable → your app can rely on stored local date

• SDK: Native integration for Unreal Engine with Blueprint/C++ events
• REST API: Universal HTTP endpoint compatible with any system
• You can use both — the SDK actually uses this endpoint under the hood

• ✔️ No API key rotation needed
• ✔️ No rate limit under normal usage
• ✔️ Encrypted database storage and HTTPS endpoint
