Outer

Outer is a direct-to-consumer outdoor furniture brand founded in 2017 by Jiake Liu and Terry Lin and headquartered in Santa Monica, California, known for its OuterShell built-in cushion cover, OuterWeave wicker and OuterCloud cushions, and for the Neighborhood Showroom program that turns customer backyards into showrooms. Outer publishes no traditional developer program and no OpenAPI, but its Shopify-hosted storefront at liveouter.com serves a real machine-readable agent surface: an /llms.txt and /agents.md agent instruction document, a Universal Commerce Protocol (UCP) merchant profile at /.well-known/ucp advertising catalog search, cart, checkout, fulfillment, discount and order capabilities, a UCP MCP endpoint at /api/ucp/mcp, and OAuth 2.0 / OpenID Connect discovery documents for the Shopify Customer Account API.

Outer publishes 1 API on the APIs.io network. Tagged areas include Company, Retail, E-Commerce, Consumer Goods, and Furniture.

Outer’s developer surface includes engineering blog, support, signup flow, authentication, and 13 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/outer: open an issue to ask a question, or submit a pull request to add artifacts.
