This topic has already been discussed before on the Shopify community. If you could spend your valuable time on this conversation, then I believe you can get an answer.

Thanks for the reply, I read the answer but I don't want to use a specific pattern.

I want the logic like on the checkout page that checks for every domain that can be given to it whether it is a real domain or not!  

Is this possible?

Based on my research, unfortunately, Shopify doesn't provide a direct API for accessing their internal email domain validation logic that's used in the checkout. However, I can help with a third-party service, DeBounce Integration by integrating the DeBounce into your Shopify forms API and adding your domain to the approved domain lists.

Here is the detailed info: https://debounce.io/integrations/shopify/
You can explore this code for further info.

async function validateEmailWithAPI(email) {
  try {
    const response = await fetch(`https://api.debounce.io/v1/?api=${YOUR_API_KEY}&email=${email}`);
    const result = await response.json();
    return result.debounce.result === 'Safe';
  } catch (error) {
    console.error('Email validation error:', error);
    return false;
  }
}

I hope this could helps.
