 ['Content-Type' => 'application/json'],
        'body' => wp_json_encode([
            'secret_key' => get_option('captchacc_secret_key', ''),
            'proof_token' => $proofToken,
        ]),
    ]);

    if (is_wp_error($response)) {
        return false;
    }

    $body = json_decode(wp_remote_retrieve_body($response), true);
    return !empty($body['success']);
}

Use that helper in your form handler, shortcode action, REST endpoint, login flow, or comment submission hook.
