3N TECH

3N TECH (Suzhou 3N Biological Technology Co., Ltd.) is a Chinese eye-care medical-device maker founded in 2015 and headquartered in Suzhou Industrial Park BioBAY, with an international arm selling in Hong Kong and the United States. It develops active contact-lens care hardware built on its patented Electrophoresis-Disintegration ("Elepy") technology, and shipped the first contact-lens cleaner to hold an FDA 510(k) clearance for that mechanism. The company sells under two brands: 3N in mainland China and ReO2 internationally, through the 3N Eyecare direct-to-consumer storefront. 3N TECH publishes no developer program and no OpenAPI. Its only machine-readable, publicly callable surface is the agentic-commerce layer on its own storefront host: an anonymous UCP (Universal Commerce Protocol) merchant profile at /.well-known/ucp.json, an unauthenticated MCP endpoint at /api/ucp/mcp serving 13 cart, checkout, order and catalog tools, an llms.txt / agents.md pair of agent instructions, and Shopify Customer Account OAuth 2.0 / OpenID Connect discovery documents. That surface is platform-authored by Shopify and served under the company's domain, which this profile records explicitly rather than crediting it as first-party API design.

3N TECH publishes 1 API on the APIs.io network. Tagged areas include Company, Eye Care, Medical Devices, Consumer Health, and Contact Lenses.

3N TECH’s developer surface includes documentation, engineering blog, support, signup flow, authentication, and 16 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.
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/3ntech: open an issue to ask a question, or submit a pull request to add artifacts.
