Tag @urls with a prompt to generate an app or a game. I will reply with a frame to try out your new creation. 

/urls telegram: t.me/urlsdotart

let's try something

@urls make a webapp that is a simple form. the form contains: 

* a textbox with a label of `message`
* a textbox with a label of `post-url`
* a button that says `submit`

when the user clicks the `submit` button, the webapp should: 

* validate that the textboxes are not empty. show a friendly error message if either of the textboxes are empty
* validate that the value of the post-url textbox is a valid url. do not test if the url is live - just that the value of the textbox matches the pattern of a valid url
* if the textbox is not empty: make a POST request to the value of the post-url textbox, with a JSON body of: { "message": "[the value of the message textbox on the form]" }
* if the response from the POST is non-200, then show the status as an error message, and show a scary emoji animation
* if the response is 200, then show a wonderful success animation
