Validator API Research

Posting a document as the HTTP request. Looks like it can be done through JavaScript in the form of an AJAX call.

This method—POSTing a document as the HTTP entity body of a request—is the recommended way to use the checker as a Web service.

To use this method to check a document:

• Issue an HTTP request with a URL for an existing checker instance such ashttps://validator.w3.org/nu/ or https://validator.nu/.
• Use the POST method for the request.
• Include the document to check as as the entity body of the request.
• Include the Content-Type request header to communicate the MIME type of the entity body; e.g., Content-type: text/html; charset=utf-8.
• Encode common parameters as query-string parameters; that is, just as you would with a GET request.
