-- Formát: JSON (messages, temperature, atď.).
+DAIAPI je proprietarne API, ktore sa da pouzivat volanim na VPN adresu 10.2.8.1 a port 9001, prakticka implementacia v PHP:
+
+```php
+function daiAPIrun(string $prompt): ?string
+{
+    $url = "http://192.168.122.10:9001/run";
+    $payload = json_encode([
+        "prompt" => $prompt
+    ]);
+    if ($payload === false) {
+        return null;
+    }
+    $ch = curl_init($url);
+    curl_setopt_array($ch, [
+        CURLOPT_RETURNTRANSFER => true,
+        CURLOPT_POST => true,
