Can any one explain why we are adding `--enable-api --cors “*”` flag in `rasa run --model models --enable-api --cors “*” --debug -p $PORT`?. Like I know this command is used to start the rasa server but I haven’t understood the use of `cors "*"` and `enable-api`. ---

From the [docs](https://rasa.com/docs/rasa/command-line-interface#rasa-run): - `--cors [CORS ...]`: Enable CORS for the passed origin. - `--enable-api`: Start the web server API in addition to the input channel. If you don’t know what CORS is, check out [CORS in 100 Seconds](https://www.youtube.com/watch?v=4KHiSt0oLJ0). `--cors "*"` basically means you are allowing any URL to make requests to the server. For example: - `cors "https://example.com/*"` means you allow requests from any page on `example.com` only. - `cors "https://example.com/chatbot"` means you allow requests from `example.com/chatbot` only. And `--enable-api`, well, enables the [API](https://rasa.com/docs/rasa/pages/http-api).
