Rael

Rael is a holistic personal-care brand founded in 2017 by three Korean-American women and led by co-founder and CEO Yanghee Paik, selling organic-cotton period care, intimate care, skincare and cycle supplements direct to consumers at getrael.com and through Target, Amazon, Walmart and Thrive Market. Rael runs no developer program, publishes no OpenAPI and ships no SDK — but its storefront serves two live, anonymous, machine-readable contracts on its own domain. The first is an agentic commerce surface Rael documents itself: a hand-written llms.txt and agents.md, a Universal Commerce Protocol merchant profile at /.well-known/ucp declaring UCP 2026-04-08, and an MCP endpoint at /api/ucp/mcp that answers tools/list with thirteen catalog, cart, checkout and order tools carrying full JSON Schema inputs and a required idempotency key on checkout completion. The second is the Shopify Storefront GraphQL API at /api/graphql, fully introspectable without a credential — 422 types, 34 queries and 41 mutations resolving against Rael's own catalog.

Rael is listed with 2 APIs on the APIs.io network. Tagged areas include Company, Retail, E-Commerce, Consumer Goods, and Health and Wellness.

Rael’s developer surface includes authentication, support, engineering blog, signup flow, documentation, and 21 more developer resources.

Kin Score

Kin Score Kin Score How this is scored →
scored 2026-10-31 · rubric v0.25.0
Regulatory Posture applies to this provider. Its tags matched the Health 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
  • Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
  • 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
4 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
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/rael/apis.yml: open an issue on github.com/api-evangelist/rael to ask a question or point us at an artifact you publish.
