// Send welcome email using Nexus
public function sendWelcomeEmail(): array {
    return Nexus::email()
        ->provider('brevo')  // or 'smtp'

        ->to($this->emailAddress)
        ->subject('Welcome to Our Platform!')
        ->html('

Thanks for joining us!
')
        ->send();
}

// Quick method
Nexus::sendEmail('[email protected]', 'Welcome!', '
Hello World
');

HTTP API Calls

Automatic JSON, headers, retries 
// GET with JSON parsing
$response = Nexus::http()->get('https://api.example.com/users');

// POST with auth
$result = Nexus::http()
    ->withHeaders([
        'Authorization' => 'Bearer ' . $token,
        'Content-Type' => 'application/json'
    ])
    ->post('https://api.example.com/orders', [
        'product_id' => 123,
        'quantity' => 2
    ]);

if ($result['success']) {
    // handle success
}

Object Storage

// Upload file
$result = Nexus::storage()
    ->provider('local')
    ->path('/var/www/storage')
    ->put('uploads/avatar.jpg', $fileContent, [
        'user_id' => 123,
        'uploaded_at' => date('c')
    ]);

// Exists and metadata
$exists = Nexus::storage()->exists('uploads/avatar.jpg');
$info   = Nexus::storage()->metadata('uploads/avatar.jpg');

// List with prefix
$files = Nexus::storage()->list('uploads/', 10);

Your First Nexus Call

A simple example showing how easy it is to integrate services 
<?php
class UserController extends Controller {
    public function welcome(): void {
        $result = Nexus::email()
            ->provider('brevo')  // or 'smtp'
            ->from('[email protected]', 'Zenith App')
            ->to('[email protected]')
            ->subject('Welcome to Zenith!')
            ->html('<h1>Welcome!</h1><p>Thanks for joining us!</p>')
            ->send();

        if ($result['success']) {
            Nexus::storage()
                ->provider('local')
                ->put('welcome-log.txt', 'User welcomed at ' . date('Y-m-d H:i:s'));
        }

        $this->render('welcome', ['success' => $result['success']]);
    }
}
