LYST

Lyst is a global fashion aggregation and shopping platform that consolidates products from more than 27,000 brands and retailers, connecting roughly 160 million annual shoppers with clothing, shoes, bags, accessories and jewelry across a single personalized, AI-driven catalog. Rather than a public developer API, Lyst exposes a partner surface: brands and retailers integrate via product-feed synchronization and a Stripe-powered "Lyst Shop" checkout, with API access granted privately during a two-week partner onboarding. Backed by Accel and Balderton Capital, Lyst also runs an engineering organization (making.lyst.com, github.com/lyst) best known for the open-source LightFM recommendation library.

LYST is profiled on the APIs.io network. Tagged areas include Company, Consumer, Fashion, E-Commerce, and Shopping.

LYST’s developer surface includes engineering blog, support, signup flow, and 5 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/.

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 github.com/api-evangelist/lyst: open an issue to ask a question, or submit a pull request to add artifacts.

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
Fashion & Apparel (apparel, footwear, textiles)	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.
