Rhizome Ai

Rhizome AI is an AI-powered regulatory research platform for pharmaceutical and medical device companies. It lets regulatory affairs teams ask questions and receive cited answers grounded in primary-source documents from health authorities worldwide (FDA, EMA, Health Canada, Swissmedic, MHRA, TGA and others across 10+ agencies), retrieving from up to a thousand documents without hallucinating. Beyond the web application, Rhizome AI publishes an enterprise HTTP API that exposes BM25 keyword search across the regulatory document corpus and full-text, page-by-page document retrieval, authenticated with an x-api-key header. A YC-backed company, Rhizome AI was surfaced as a portfolio-company lead and enriched from its public developer documentation.

Rhizome Ai publishes 1 API on the APIs.io network: Documents API. Tagged areas include Company, Regulatory, Pharmaceuticals, Medical Devices, and Life Sciences.

Rhizome Ai’s developer surface includes documentation, API reference, getting-started guide, authentication, support, pricing, signup flow, and 17 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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/rhizome-ai: open an issue to ask a question, or submit a pull request to add artifacts.
