Debut

Debut (Debut Biotechnology, Inc.) is a San Diego, California biotechnology company founded in 2019 by Dr. Joshua Britton that combines AI-driven molecular discovery, skin genomics and cell-free biomanufacturing to create novel cosmetic active ingredients and finished skincare formulations. Its BeautyORB platform screens billions of candidate molecules in silico against a skin-health genomic dataset, and the company is vertically integrated from discovery through fermentation, scale-up and formulation, selling ingredients and brand-ready products to beauty manufacturers as well as running its own direct-to-consumer skincare brand, DEINDE. Debut has raised roughly $89M across Series A, Series B (led by BOLD, the L'Oreal venture fund) and later rounds, employs more than 80 people, and was named to the TIME100 Most Innovative Companies 2025. Debut sells molecules and formulations rather than software: debutbiotech.com publishes no developer program, no public API and no machine-readable API contract. Its only agent-reachable API surface is the Shopify-hosted Universal Commerce Protocol (UCP) MCP endpoint on its DEINDE storefront at www.deinde.com, which is live, unauthenticated for catalog and cart operations, and returns full JSON Schema tool definitions.

Debut is listed with 1 API on the APIs.io network. Tagged areas include Company, Biotechnology, Beauty, Cosmetics, and Skincare.

Debut’s developer surface includes engineering blog, product news, support, documentation, authentication, and 21 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
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
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)

6 more unmet checks in the Agent Readiness table above.

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

Contract Quality scores 0.0 — up to +25.0 composite points
Access Clarity scores 21.1 — up to +15.8 composite points
Developer Ergonomics scores 30.4 — 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/debut/apis.yml: open an issue on github.com/api-evangelist/debut 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
Chemistry and Materials (chemical data depositors, materials-data APIs)	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 1

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.
