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

    Directory and Payer-to-Payer exchange for the Optum behavioral and physical health plans. The former developer.optum.com/dataaccessandinteroperability
    ReadMe project no longer resolves (every path returned the portal shell when probed on 2026-08-14); the developer information
    is now published as per-plan PDF packets on optum.com, so there is no machine-readable contract for this surface.
