Serif Health

Serif Health turns federal hospital and payer price-transparency disclosures (machine-readable files) into normalized, decision-ready negotiated-rate data. Its REST APIs let teams query negotiated reimbursement rates and rate distributions by CPT/DRG code, payer, provider, and geography, search for in-network providers, and pull custom datasets and extracts.

Serif Health publishes 2 APIs on the APIs.io network: Distributions API and Rates API. Tagged areas include Healthcare, Price Transparency, Negotiated Rates, Payer, and Data.

Serif Health’s developer surface includes authentication, documentation, engineering blog, and 9 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 does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

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