Zenflow

Zenflow is a San Francisco-based medical device company founded in 2014 (Y Combinator W15) that develops the Zenflow Spring, a small permanent implant delivered in a minimally invasive in-office procedure to relieve urinary obstruction caused by benign prostatic hyperplasia (BPH). The company positions the Spring as a long-lasting alternative to daily BPH medications and to more invasive surgical procedures, avoiding their side effects and recovery burden. Zenflow is a medical-device / hardware company and does not publish a public API, developer platform, SDKs, MCP server, or webhooks; this record is maintained in the API Evangelist network as a company profile.

Zenflow is profiled on the APIs.io network. Tagged areas include Company, Medical Devices, Healthcare, MedTech, and Urology.

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/zenflow: open an issue to ask a question, or submit a pull request to add artifacts.
