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.
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/.

  note: Defunct company (acquired by GlaxoSmithKline 2008, later dissolved); sirtris.com is now a parked/for-sale domain (all
    paths incl. /.well-known/* return an identical lander stub, wildcard 200) and api.sirtris.com has no valid TLS cert. No
    API surface, developer portal, docs, or spec exists to enrich.
