The leading Groundhog Day data source

Groundhog Day API

The GROUNDHOG-DAY.com API returns all of North America's prognosticating animals and their yearly weather predictions. Our innovative LLM (Largely Luck-based Marmot) model is trained on over 130 years of data, and can be used to make inferences about whether spring will come early or not. It’s the critical infrastructure you need for your next multi-billion-dollar business venture.
