Perfect Day
Perfect Day is a Berkeley, California food-technology company, founded in 2014, that makes animal-free dairy proteins with precision fermentation. Rather than farming cows, Perfect Day ferments microflora carrying milk's protein-coding genes to produce ProFerm, a non-animal whey protein with no lactose, cholesterol, hormones or antibiotics, which it sells business-to-business to consumer brands making ice cream, cream cheese, milk, yogurt, protein powders and bakery products. The company is a member of the Precision Fermentation Alliance. Perfect Day publishes no product or developer API; the single machine-readable surface it operates is the WordPress REST API (wp/v2) behind perfectday.com, which exposes anonymous read access to its blog posts, newsroom items, success stories, pages, media, taxonomies and site search, plus authenticated write operations via WordPress application passwords. This profile was enriched by the API Evangelist pipeline from that live surface.
Perfect Day publishes 16 APIs on the APIs.io network, including Categories API, Comments API, Leader Category API, and 13 more. Tagged areas include Company, Food Technology, Precision Fermentation, Alternative Protein, and Ingredients.
Perfect Day’s developer surface includes documentation, API reference, engineering blog, support, FAQ, authentication, and 25 more developer resources.
