<p>Checks Domain WHOIS Lookup for availability. Simple insert the [pwhois] shortcode on a page or post.<br />
To select the default TLD use the default attribute: [pwhois default=com] – sets .com as default in the TLD dropdown.<br />
TLD List is limited because of the knowledge of the required whois servers. If you wish to have support for a special TLD please contact me and I will implement it asap.<br />
We cannot guarantee that every domain lookup works perfect, in case that whois servers and how to talk to them can change time by time.<br />
However if you inform us about changes and we can get it to work, we give you a free version of the Pro version of this plugin!</p>

Powie's WHOIS Domain Check

Not what I needed. It can only check availability for .com domains, not any TLD as in description. One star for inaccurate description.

LIMITED – only checks .com

Fetchify

<p>This plugin can be configured to provide up to 4 different data validation products. It replaces our previous plugins Crafty Clicks Address Auto-Complete and Crafty Clicks Postcode Lookup.</p>
<h4>Address Auto-Complete</h4>
<p>Adds address auto-fill, lookup and validation to address forms on the front-end in WooCommerce for over 240 countries.</p>
<p>The checkout experience becomes faster and easier as a customer no longer has to type out their full address. The smart predictive search helps speed up form filling and boosts usability. Every address is verified at the point of entry. Problems due to incorrect or badly typed address data are drastically reduced.</p>
<h4>Postcode Lookup</h4>
<p>The defacto solution for address capture and validation in the UK. Enter any UK postcode in the search field, click the search button and the drop down will show all the relevant address results for that postcode. Select the required address and the form will immediately be populated with accurate information.</p>
<h4>Phone Validation</h4>
<p>Verifies all number types and formats including mobile, international and landline numbers in every country/territory worldwide. Corrects and re-formats common mistakes within forms to ensure data quality.</p>
<h4>Email Validation</h4>
<p>Email Validation provides real-time validation of any email address. Invalid format emails are declined immediately while valid emails are checked to ensure they link to an active provider. The API verifies username and domain elements of the email address.</p>
<h4>Customer Satisfaction & Conversions</h4>
<p>Easier and faster checkout saves your customers’ time, improves conversions and builds loyalty.</p>
<h4>Data Quality</h4>
<p>User input is validated in real time and your customer database is populated with fully verified addresses, phone numbers and email addresses. Address verification can reduce failed deliveries by up to 50%.</p>
<h4>WPML Compatibility</h4>
<p>This plugin is compatible with WPML to make your checkout multilingual. To find out more about WPML go to https://wpml.org/</p>
<h4>Getting Started</h4>
<p>In order to use this service, you will need to sign up for an account. You will then receive an access token which will give you access to our service. You need to insert this access token in the configuration options. We offer 30 free searches for testing purposes, but in order to use this plugin on a live site, you must have a paid account with us.</p>
<h4>Automatic Updates</h4>
<p>Our service is split into 3 parts:</p>
<ol>
<li>An API server that delivers the data</li>
<li>A JS library that can retrieve the data, and generate a basic UI, regardless of platform</li>
<li>WooCommerce specific JS files (located in clicktoaddress-auto-complete/frontend/js and clicktoaddress-auto-complete/admin/js)</li>
</ol>
<p>The JS library is located on our CDN to ensure that you will automatically receive any updates. If there’s an update to the API and changes to the JS library are required in order for the plugin to function correctly, you will not have to worry about updating it yourself.</p>


This plugin adds global address auto-complete functionality to the address forms on the front-end in WooCommerce.
