 * **Quota**: ?
+* **HTTP Headers**: in order to use the licensed API you can configure the http_headers to include a referer as so:
+    `Geocoder::Configuration.http_headers = { "Referer" => "http://foo.com" }`
+  You can also allow a blank referer from the API management console via mapquest but it is potentially a security risk that someone else could use your API key from another domain.
