Ciitizen

Ciitizen is a digital health company that helps patients collect, organize, and control their own medical records. Founded by Anil Sethi and backed by a16z, Ciitizen built patient-directed tools for aggregating records across providers under HIPAA right-of-access, originally with a focus on cancer patients. The team and technology now operate as Citizen Health (citizen.health), which turns a patient's medical records into instant answers through an AI Advocate built for rare disease patients and caregivers and used by 100+ patient advocacy groups. Ciitizen exposes no public developer API, developer portal, or machine-readable API artifacts at this time; this profile captures the company identity and its live web presence.

Ciitizen is profiled on the APIs.io network. Tagged areas include Company, Healthcare, Health Records, Patient Data, and Rare Disease.

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