Supergoop!

Supergoop! is a prestige suncare brand founded in 2005 by Holly Thaggard and headquartered in San Antonio, Texas, selling SPF-first skincare, body, makeup and kids products direct-to-consumer at supergoop.com and through retail partners; Blackstone Growth took a majority stake in 2021 at a reported $600-700 million valuation. It is not a software company and runs no developer program, but its Shopify storefront exposes three live, anonymous machine surfaces on its own domain: a Universal Commerce Protocol (UCP) shopping MCP server at /api/ucp/mcp with 13 tools, a fully introspectable Storefront GraphQL API at /api/2026-07/graphql.json with 428 types, and agent-facing instructions at /agents.md and /llms.txt that publish the discovery paths, the six-step agent purchase flow and a hard human-approval rule on payment.

Supergoop! is listed with 2 APIs on the APIs.io network. Tagged areas include Company, Sunscreen, Skincare, Beauty, and Cosmetics.

Supergoop!’s developer surface includes documentation, support, signup flow, authentication, code examples, and 24 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):

Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too
Dry-Run / Simulate Mode +4 pts — OpenAPI: destructive operations expose a dry_run / simulate / preview / validate_only parameter

Kin Score — facets with the most composite points still available (weight × headroom):

Developer Ergonomics scores 28.0 — up to +14.4 composite points
Contract Quality scores 44.6 — up to +13.9 composite points

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/supergoop/apis.yml: open an issue on github.com/api-evangelist/supergoop to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Consumer Goods (product data and retail supply chain)	undeclared	-	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

GraphQL

tagged — the provider's own APIs.json carries the standard as a tag; implementation not verified
