There is an API available online that responds with a number (number of points) when you submit a GET request to a certain URL.
I'd like my Google Home to say this information when I ask it to. I have attempted to do this with DialogFlow but I'm not sure how I would go about doing it.
EDIT: I used the DialogFlow fulfillment webhook feature. DialogFlow sends a post request to my webserver and the server responds with "fulfillmentText" which is what the Google Home will say.
There is nothing built-into Google Home that will get information out of the page at a URL.
You can write a program that will be triggered by the Assistant using Actions on Google. This includes something that would run through Dialogflow, or it could run through the Actions SDK. Either way - you would do this by writing a program that would be called in a webhook to fetch the data and return a message that would be read by the Assistant on your Home.
