+## Detect
+
+The `detect` action attempts to redirect the user to an appropriate `display` action for a feed based on a supplied URL. As bridges have to individually implement this it may not work for every bridge.
+
+If an appropriate bridge is found, a `301 Moved Permanently` HTTP status code is returned with a relative location for a `display` action. If no appropriate bridge is found or a required parameter is missing, a `400 Bad Request` status code is returned.

+The parameters for this action are listed bellow:

 ## List
 
 The `list` action returns a JSON formatted text containing information on all bridges available to the current instance of RSS-Bridge. Inactive bridges (not [whitelisted](Whitelisting)) are included as well. Broken bridges are also included, but with limited parameters (only `"status": "inactive"`).
