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 is listed with 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.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

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 the provider profile at artifacts.apis.io/outer/apis.yml: open an issue on github.com/api-evangelist/outer to ask a question or point us at an artifact you publish.
