Groundhog Profile and Prediction History by Slug (Groundhog-Day.com)

groundhogday/groundhog-lookup

One Groundhog Day prognosticating animal by its URL slug (for example punxsutawney-phil or wiarton-willie): its profile (name, city, region, country, type, description, source page, image URL, whether it is active, its successor if any) and every prediction on record, one entry per year with `shadow` (1 saw its shadow, which the legend reads as six more weeks of winter; 0 no shadow, early spring; null no recorded prediction that year) and the day's notes. latitude and longitude are numbers. An unknown slug is refused as VALIDATION. Data from Groundhog-Day.com, served by Eden Engine; not an official Groundhog-Day.com product.
