Hubble Contacts

Hubble Contacts is a New York-based direct-to-consumer vision care brand that sells prescription contact lenses, eyeglasses, sunglasses and eye care accessories on a personalized subscription model, shipping daily, weekly and monthly lenses — its own Classic, Hydro and SkyHy lines alongside third-party brands such as Acuvue, Bausch + Lomb, Biotrue and DAILIES — direct to customers at prices it advertises as up to 30% below comparable retail. Its public machine-readable surface is not a developer API but an agent-commerce one: the storefront at account.hubblecontacts.com publishes /llms.txt and /agents.md, a Universal Commerce Protocol (UCP) merchant profile at /.well-known/ucp, an MCP endpoint at /api/ucp/mcp for agent-driven catalog search, cart, checkout and order flows, OAuth 2.0 / OpenID Connect customer account discovery documents, and unauthenticated read-only product and collection JSON endpoints. Undocumented but wide open beside them sits the full Shopify Storefront GraphQL API on the same host — 416 types, anonymous, introspectable, and the only place the company's subscription selling plans are modelled.

Hubble Contacts publishes 3 APIs on the APIs.io network. Tagged areas include Company, E-Commerce, Retail, Health, and Vision Care.

Hubble Contacts’ developer surface includes signup flow, pricing, support, engineering blog, documentation, authentication, 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/.

    own host at /api/{version}/graphql.json, which round 1 had missed by probing /graphql on the wrong host, plus a first-party
    Postman collection for an archived Doctor/ECP API in Hubble's GitHub org. No OpenAPI, no A2A agent card, no AsyncAPI/webhooks,
    no SDKs, no security.txt and no trust center exist on any Hubble host.

    It answers unauthenticated: full introspection and real data queries both return 200 with no storefront access token,
    and the server labels the call storefront/query/anonymous. 416 types, 35 root queries and 41 mutations cover the catalog
    (products, prescription variants, options, collections, price ranges, availability), subscription selling plans — which
    appear on no other Hubble surface even though subscription is the company''s business model — content (blogs, articles,
    pages, menus), localization and payment settings, cart creation and line editing through to submission for completion,
    and customer account management. Relay cursor pagination, a per-query cost budget in extensions.cost plus shopify-complexity-score
    headers, 55 @deprecated fields with machine-readable reasons, and a publicApiVersions query that reports its own supported
    version window. Hubble links to none of it: it appears in neither /agents.md, /llms.txt nor /.well-known/. Schema captured
    by live introspection.'
