Techstyle Fashion Group

TechStyle Fashion Group is the El Segundo, California holding company founded in March 2010 by Don Ressler and Adam Goldenberg as JustFab Inc. and renamed TechStyle Fashion Group in August 2016. It builds and operates direct-to-consumer membership fashion brands on a shared, proprietary commerce and personalization platform once marketed as TechStyle OS — Fabletics (with the Yitty shapewear line), Savage X Fenty, JustFab, ShoeDazzle and FabKids — selling apparel, footwear, activewear, intimates and accessories through a VIP membership subscription that gives members monthly credits, member pricing and a monthly skip window. The group reported more than five million paying VIP members and roughly $800 million in revenue as of 2019, and has since reorganized so that Fabletics, Savage X Fenty and the Global Fashion Brands unit (JustFab, ShoeDazzle, FabKids) run as standalone operating companies on the shared supply chain, fulfillment and technology stack. The TechStyle corporate identity itself has been retired: both techstyle.com and techstyleos.com now redirect to a Gandi domain-parking page at techstylefashiongroup.com that answers on plain HTTP only, so the group publishes no corporate site, no developer program, no API reference and no machine-readable contract of its own. The live API surface belongs to the operating brands, which are profiled separately in this network.

Techstyle Fashion Group is profiled on the APIs.io network. Tagged areas include Company, Fashion, Apparel, Retail, and E-Commerce.

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
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
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

13 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
Developer Ergonomics scores 0.0 — up to +20.0 composite points
Access Clarity scores 0.0 — up to +20.0 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/techstyle-fashion-group/apis.yml: open an issue on github.com/api-evangelist/techstyle-fashion-group 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.

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.
