Syapse was a San Francisco precision-medicine software company, founded in 2008, that built a real-world evidence platform for community oncology. Its product integrated structured clinical data from health-system EHRs with genomic/NGS results to support molecular tumor boards, care coordination, quality improvement and life-sciences research, and it ran the Syapse Learning Health Network of community health systems alongside collaborations with Roche, Amgen and the US Department of Veterans Affairs. Syapse Holdings was acquired by N-Power Medicine in a stock-for-stock exchange that closed 2024-12-30 and was announced 2025-01-12; its network of 1,000+ community oncologists, its data and technology stack, and its team were folded into N-Power Medicine's always-on community clinical-research model. The Syapse brand has since been fully retired: syapse.com now serves nothing but a 292-byte meta-refresh stub redirecting to npowermedicine.com, dated 2025-01-12. Syapse never published a public developer program, and no public API, OpenAPI/AsyncAPI/GraphQL contract, SDK or developer portal survives.
Syapse is profiled on the APIs.io network. Tagged areas include Company, Healthcare, Oncology, Precision Medicine, and Real-World Evidence.
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/syapse: open an issue to ask a question, or submit a pull request to add artifacts.

detail: 'Syapse was fully absorbed into N-Power Medicine (stock-for-stock, closed 2024-12-30) and its entire web property
was retired the same week: syapse.com and www.syapse.com now answer every path — including an invented control path —
with the identical 292-byte HTML meta-refresh stub to npowermedicine.com, Last-Modified 2025-01-12, so there is no docs
host, no API host and no contract left to read.'
