server/general: rename _fields to fields

API.md

@@ -129,14 +129,14 @@ For performance considerations, sometimes the client might want to choose the
 fields the server sends to it in order to improve the query speed. This
 customization is available for top-level fields of most of the
 [resources](#resources). To choose the fields, the client should pass
-`?_fields=field1,field2,...` suffix to the query. This works regardless of the
+`?fields=field1,field2,...` suffix to the query. This works regardless of the
 requesttype (`GET`, `PUT` etc.).
 
 For example, to list posts while getting only their IDs and tags, the client
 should send a `GET` query like this:
 
 ```
-GET /posts/?_fields=id,tags
+GET /posts/?fields=id,tags
 ```
