Matchaful

Matchaful is a premium Japanese matcha brand selling single-origin, organically-grown ceremonial matcha from Shizuoka, Japan — ground to order, pesticide-free, and third-party tested under its Farm-to-Whisk program. It sells direct-to-consumer through a Shopify storefront and runs physical cafes, and is a Techstars portfolio company. Matchaful publishes no traditional developer REST API or OpenAPI, but its Shopify storefront exposes a live agent-commerce surface: an /llms.txt and /agents.md agent instruction set, a Universal Commerce Protocol (UCP, ucp.dev) merchant profile at /.well-known/ucp, a first-party MCP shopping endpoint at /api/ucp/mcp, and Shopify Customer Account OIDC/OAuth discovery documents served under the store domain.

Matchaful publishes 1 API on the APIs.io network. Tagged areas include Company, Matcha, Tea, Food and Beverage, and CPG.

Matchaful’s developer surface includes engineering blog, signup flow, support, and 7 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/matchaful: open an issue to ask a question, or submit a pull request to add artifacts.
