function verishield_verify(string $email): array {
    $ch = curl_init('https://verishield-edge-api.p.rapidapi.com/v1/verify');
    curl_setopt_array($ch, [
        CURLOPT_POST => true,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_HTTPHEADER => [
            'Content-Type: application/json',
            'X-RapidAPI-Key: ' . getenv('RAPIDAPI_KEY')
        ],
        CURLOPT_POSTFIELDS => json_encode(['email' => $email]),

    ]);
    $data = json_decode(curl_exec($ch), true);
    curl_close($ch);
    return $data;
}

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.
