ColdSnap

ColdSnap (formerly Sigma Phase, Corp.) is a Billerica, Massachusetts hardware and frozen-confection company founded in October 2018 by Matt Fonte, whose plug-and-play countertop appliance chills and churns a single serving of premium ice cream, frozen yogurt, non-dairy dessert, frozen latte, protein shake, smoothie or frozen cocktail from a shelf-stable recyclable pod in about two minutes, with no refrigeration, plumbing or cleaning between servings. The company commercially launched in April 2024 and sells machines, pods and accessories to restaurants and bars, hotels, golf and sports clubs, colleges, senior living, car dealerships, offices, convenience stores and micro markets. Its digital surface is a Shopify-hosted commerce storefront at coldsnap.com serving a live, anonymously introspectable Storefront GraphQL API, an anonymous Model Context Protocol server at /api/mcp, a Universal Commerce Protocol (UCP) merchant profile and agentic-commerce endpoint, plus published llms.txt and agents.md agent-instruction documents.

ColdSnap publishes 3 APIs on the APIs.io network. Tagged areas include Company, Commerce, E-Commerce, Retail, and Food and Beverage.

ColdSnap’s developer surface includes documentation, getting-started guide, support, engineering blog, pricing, YouTube channel, authentication, and 32 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/coldsnap: open an issue to ask a question, or submit a pull request to add artifacts. Submit an artifact on GitHub — free → Manage your own listing — the Influence plan, $499/mo →
