Founded by two Harvard Medical School professors, Aetion was acquired by Datavant; the acquisition closed 11 July 2025 and Aetion now operates inside Datavant's Life Sciences business.

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/.

  detail: Aetion was absorbed into Datavant when the acquisition closed on 11 July 2025, and every path on aetion.com — including
    /.well-known/* — now answers HTTP 301 into www.datavant.com, so there is no Aetion-origin developer surface left to read;
    the only Aetion host still serving anything of its own is the customer support portal at support.aetion.com, a Salesforce
    Experience Cloud community.
