Not valid because there are no plugins: "These calls will be allowed for NGINX depending on how you have implemented the mapping for your plugin. For the following call, it will be up to your application to return a 404 not found response. To avoid this, refine the mapping:"

Also "With the code plugin, you need to decide which type to implement. On the other hand, APIcast defines hard limits by default. These can be customized in the Lua file to avoid rejecting over-limit calls." is not valid.
