Using Facade Class

$response = \Msr\LaravelBitunixApi\Facades\LaravelBitunixApi::changeLeverage('BTCUSDT', 'USDT', 12);

Using implemented contracts class

$api = new \Msr\LaravelBitunixApi\LaravelBitunixApi();
$response = $api->changeLeverage('BTCUSDT', 'USDT', 12);

Using Contracts

which bind in package service provide (LaravelBitunixApiServiceProvider)

Troubleshooting

API credentials not loading from .env

Make sure your .env file is in the project root
Check that the variable names match exactly (case-sensitive)
Restart your application/server after changing .env
Clear config cache: php artisan config:clear

Signature generation fails

Verify API key and secret are correct
Check that the credentials have the necessary permissions
Ensure your system time is synchronized

Security

Never commit API credentials to version control
Use environment variables for all sensitive data
Restrict API key permissions to minimum required
Regularly rotate API keys
