I tried following this guide but when I test it, it is just triggering regular expression validation I want my to check postcode in API.

Here is the code in {module_name}/view/web/js/model/postalCode.js

    define(
    [
        'jquery'
    ],
    function ($) {
        'use strict';

        return {

            /**
             * Validate checkout agreements
             *
             * @returns {Boolean}
             */
            validate: function () {
                var zipValidationResult = false;
                var zip = $('form[postcode]').val();
                alert("WORKING" + zip);
                console.log("WORKING");
                return true;
            }
        };
    }
);

Here us code in {module_name}/view/web/js/view/postalCode.js :

     define(
    [
        'uiComponent',
        'Magento_Checkout/js/model/payment/additional-validators',
        'Sdu_CheckPostalCode/js/model/postalCode'
    ],
    function (Component, additionalValidators, postalCode) {
        'use strict';
        additionalValidators.registerValidator(postalCode);
        return Component.extend({});
    }
);

And here is code in {module_name}/view/frontend/layout/checkout_index_index.xml:
