Listening for a redirected GET / POST payload

I have a cheap wifi device that updates a remove server via HTTP. It isn’t supported by HASS, except through WUnderground (which is no longer free) or IFTTT (which I’d like to avoid). I’ve configured my DNS to redirect to my local HASS, but I’m not sure the best way to ingest as a sensor. Is there a way to component that will listen/respond/parse this without configuring a separate web server? Here is a snippet from my packet capture:
