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 publishes 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.

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.
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/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/rael: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
