- Composer
- Laravel 11
- Database (MySQL/PostgreSQL)
- Code editor
- Terminal/Command prompt
Materials needed:
- OpenAI API key
- Composer packages

Project Setup and Configuration
Step 1: Initial Setup
# Create new Laravel project
composer create-project laravel/laravel openai-proxy
# Install required packages
composer require openai-php/client
composer require guzzlehttp/guzzle
composer require filament/filament:"^3.0-stable"
Step 2: Environment Configuration
OPENAI_API_KEY=your_api_key_here
APP_URL=your-domain.com
Core Components Implementation
1. API Key Management
// app/Models/ApiKey.php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Str;
class ApiKey extends Model
{
protected $fillable = ['name', 'key'];
public static function generateUniqueKey(): string
{
return 'pk_' . Str::random(32);
}
}
2. OpenAI Proxy Controller
// app/Http/Controllers/OpenAIProxyController.php
namespace App\Http\Controllers;
use OpenAI;
use Illuminate\Http\Request;
class OpenAIProxyController extends Controller
{
private function initializeOpenAI($apiKey)
{
return OpenAI::client($apiKey);
}
public function proxyChat(Request $request)
{
$client = $this->initializeOpenAI(config('services.openai.key'));
return $client->chat()->create([
'model' => $request->input('model', 'gpt-3.5-turbo'),
'messages' => $request->input('messages'),
]);
}
}
Feature Implementation Guide
1. Chat Completion Implementation
public function handleChatCompletion($messages, $model = 'gpt-3.5-turbo')
{
try {
$response = $this->openai->chat()->create([
'model' => $model,
'messages' => $messages,
'temperature' => 0.7,
]);
return $response->toArray();
} catch (\Exception $e) {
return $this->handleError($e);
}
}
2. Text-to-Speech Implementation
public function handleTextToSpeech($text, $voice = 'alloy')
{
try {
$response = $this->openai->audio()->speech([
'model' => 'tts-1-hd',
'input' => $text,
'voice' => $voice,
]);
return $response;
} catch (\Exception $e) {
return $this->handleError($e);
}
}
Security Implementation
API Key Validation
private function validateApiKey($request)
{
$apiKey = $request->header('X-API-Key');
if (!$apiKey || !ApiKey::where('key', $apiKey)->exists()) {
throw new \Exception('Unauthorized', 401);
}
return true;
}
Usage Examples
JavaScript Example
const makeRequest = async (endpoint, data) => {
const response = await fetch(`${baseUrl}/api/openai-proxy/${endpoint}`, {
method: 'POST',
headers: {
'X-API-Key': 'your_api_key_here',
'Content-Type': 'application/json',
},
body: JSON.stringify(data)
});
return await response.json();
};
PHP Example
$client = new \GuzzleHttp\Client();
$response = $client->post('https://your-domain.com/api/openai-proxy/chat', [
'headers' => [
'X-API-Key' => 'your_api_key_here',
'Content-Type' => 'application/json',
],
'json' => [
'model' => 'gpt-3.5-turbo',
'messages' => [
['role' => 'user', 'content' => 'Hello!']
]
]
]);
