Unfortunately, Splash cannot render that URL so it won't be possible to scrape with Portia. JSON responses are possible to scrape as long as Portia is able to render as HTML.

@rpm61 Enable JS in Portia and when you run the spider in Scrapinghub it should extract the JSON response.

Is that why I can't seem to get any items out of this rather simple JSON response using regex?
I do get the response to load from this url, but my annotations produce no items, it starts trying to extract and just keeps spinnin'. Is there some trick to annotations on straight JSON, or does everything need to be framed in HTML?
