Barn & Willow

Barn & Willow is a direct-to-consumer home furnishings brand specializing in made-to-measure window treatments — custom drapery, curtains, roman shades and blinds in natural fabrics such as linen, cotton and velvet.

Surfaced as a portfolio company of 500 Global and added to the API Evangelist network, the storefront exposes a real agentic-commerce surface: a Universal Commerce Protocol (UCP) merchant profile and hosted MCP endpoint for agent-driven shopping, Shopify Customer Account OAuth 2.0 / OpenID Connect authentication, and an llms.txt agent-instructions document.

Barn & Willow publishes 1 API on the APIs.io network. Tagged areas include Company, E-Commerce, Retail, Home Furnishings, and Window Treatments.

Barn & Willow’s developer surface includes authentication and 9 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/barn-and-willow: open an issue to ask a question, or submit a pull request to add artifacts.
