Sort of.

There are some experimental interfaces available,  try
output=(xml|earl|n3) in the query string.  These interfaces add various
X-W3C-Validator-* HTTP headers to the responses which may or may not be
useful so that they allow one to use HEAD requests to "hide" errors :)
Currently the headers are:

  X-W3C-Validator-Errors (number of errors found)
  X-W3C-Validator-Status ("Valid" or "Invalid")

Note that these are experimental and may change.

Close, but not quite there.  The "errors" query string parameter
controls whether unprocessed error output from the underlying SGML/XML
parser will be included in the results page.  If set to a true value (as
far as Perl is concerned that is, ie. a non-empty string which is not
"0"), a "Raw Error Output" section containing that stuff can be found at
the bottom of the results page.
