  -H "Content-Type: application/json" \
  -d '{
    "license_key": "XXXX-XXXX-XXXX-XXXX",
    "domain": "example.com"
  }'
$response = Http::withToken('YOUR_API_KEY')
    ->post('https://cothery.com/api/v1/licenses/verify', [
        'license_key' => $licenseKey,
        'domain'     => $_SERVER['HTTP_HOST'],
    ]);

if ($response->json('valid')) {
    // License is valid — unlock product
} else {
    // License invalid or expired
}
const res = await fetch('https://cothery.com/api/v1/licenses/verify', {
  method: 'POST',
  headers: {
    'Authorization': `Bearer ${API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    license_key: licenseKey,
    domain: window.location.hostname,
  }),
});

const data = await res.json();
if (data.valid) {
  // License is valid
}
import requests

response = requests.post(
