Proxy

Proxy (Y Combinator, Summer 2016) was a San Francisco digital-identity startup founded by Denis Mars and Simon Ratner that built a mobile and wearable digital wallet for payments, identity, and authentication, later expanding into biometric identity verification and vaccine-credential verification. The company was acquired by OURA in 2023; the proxy.com domain no longer resolves to an active product and there is no public developer platform, API, or documentation surface to enrich. This profile is retained as a historical/acquired-company record.

Proxy is profiled on the APIs.io network. Tagged areas include Company, Digital Identity, Authentication, Wearables, and Access Control.

Regulatory Posture applies to this provider. Its tags matched the Payments 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/proxy: open an issue to ask a question, or submit a pull request to add artifacts.
