namespace App\Rules;
use Closure;
use Illuminate\Contracts\Validation\ValidationRule;
use Illuminate\Support\Facades\Http;

class VeriShieldEmailRule implements ValidationRule {
    public function validate(string $attribute, mixed $value, Closure $fail): void {
        $response = Http::withHeaders(['X-RapidAPI-Key' => config('services.rapidapi.key')])
            ->post('https://verishield-edge-api.p.rapidapi.com/v1/verify', ['email' => $value]);
        if ($response->json('fraud_risk.recommendation') === 'BLOCK') {
            $fail('Disposable or high-risk email addresses are not permitted.');
        }
    }
}

What this protects against

Disposable and temporary inboxes, Gmail dot-trick and plus-alias multi-accounting, high-entropy bot usernames, and freshly registered fraud domains. The API returns a 0-100 fraud score with an ALLOW, CHALLENGE_2FA or BLOCK recommendation.
