Yes, you’d have to do a pull (get) on the URL (API) to pull this info down when needed.
I did my implementation via a chatbot that hits a custom glitch.com app (was a good excuse to test them) – I pull temp, probe temp, humidity, timestamp, and calculate the delay in minutes off the latter. This way, whenever I ask for it, I get my Alexa and Google Home devices reply with {temp} outside, {probe} water, {humidity}% humidity, as of {delay}.
The URL I got off the mobile app you will install to enable the bridge - when you “register” it via the app, you will be given your unique bride id, so the URL will look something like this: laxservices/device_info.php?&limit=1&timezone=8&metric=0&deviceid=XYZ
