Statistics module not effect with Services module
Statistics increments hits in hook_exit i.e:

statistics_exit

It's normally called as part of drupal_exit in drupal_page_footer

In any case, statistics_exit for the node counter actually checks

if (arg(0) == 'node' &amp;&amp; is_numeric(arg(1)) &amp;&amp; arg(2) == NULL) {}


That won't be true on an api request URL.

You might need to implement

hook_services_request_postprocess_alter

check the node request and make the stats increment call yourself.

Something like:

/**
 * Alter results of the services call.
 *
 * @param $controller
 *   Controller definition
 * @param array $args
 *   Arguments passed to services callback
 * @param array $result
 *   Array of results that can be altered
 *
 * @see services_controller_execute()
 * @see services.runtime.inc
 */
function MODULE_services_request_postprocess_alter($controller, $args, &amp;$result) {
  // Increment hit count for node view api requests.
  $nid = $result-&gt;nid; // May need to confirm this is the node id.
  if($controller['callback'] == '_node_resource_retrieve'){
    // See statistics_exit()
    if (variable_get('statistics_count_content_views', 0)) {
      // A node has been requested, so update the node's counters.
      db_merge('node_counter')-&gt;key(array('nid' =&gt; $nid))-&gt;fields(array(
        'daycount' =&gt; 1,
        'totalcount' =&gt; 1,
        'timestamp' =&gt; REQUEST_TIME,
      ))-&gt;expression('daycount', 'daycount + 1')-&gt;expression('totalcount', 'totalcount + 1')-&gt;execute();
    }
  }
}
