Cometeer

Cometeer is a Gloucester, Massachusetts coffee company, founded in 2015 by Matthew Roberts and Douglas Hoon, that brews specialty coffee at high extraction and then flash-freezes it with liquid nitrogen into single-serve capsules shipped direct to consumers by subscription. Coffees are roasted by third-wave partners including Counter Culture, Intelligentsia, Onyx, Square Mile, Equator and George Howell. Cometeer publishes no developer API, but its Shopify-hosted storefront exposes a substantial machine-readable agent surface: an /llms.txt agent instruction set, OpenID Connect and RFC 8414 authorization-server metadata on its own apex host, and a live Universal Commerce Protocol (UCP) merchant profile advertising an MCP endpoint for agent-driven cart, checkout and order flows.

Cometeer publishes 3 APIs on the APIs.io network: Collections API, Products API, and Search API. Tagged areas include Company, Coffee, Food and Beverage, E-Commerce, and Direct to Consumer.

Cometeer’s developer surface includes documentation, support, engineering blog, pricing, signup flow, authentication, and 13 more developer resources.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

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/cometeer: open an issue to ask a question, or submit a pull request to add artifacts.
