selamlar, kullanabilirsin. nodejs ve python icin official sdk'leri var ancak curl kodlarini da her ornekte paylasiyorlar, ornegin php'de kullanmak istiyorsun, curl'den php'ye cevirip kullanabilirsin.
bunu icin su siteyi kullanabilirsin: https://incarnate.github.io/curl-to-php/

ornegin asagidaki curl kodu:

curl https://api.openai.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $OPENAI_API_KEY" \
  -d '{
    "model": "gpt-3.5-turbo",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

şöyle bir php koduna dönüşüyor:

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://api.openai.com/v1/chat/completions');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "{\n    \"model\": \"gpt-3.5-turbo\",\n    \"messages\": [{\"role\": \"user\", \"content\": \"Hello!\"}]\n  }");

$headers = array();
$headers[] = 'Content-Type: application/json';
$headers[] = 'Authorization: Bearer OPENAI_API_KEY';
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close($ch);
