Centene

Centene Corporation is a Fortune 500 managed care organization delivering government-sponsored healthcare to roughly one in fifteen Americans through Medicaid, Medicare Advantage, TRICARE and Health Insurance Marketplace plans, operating under brands including Ambetter Health, Wellcare, Superior HealthPlan and Fidelis Care. Its public API surface exists to satisfy the 21st Century Cures Act and the CMS Interoperability and Patient Access Rule: HL7 FHIR R4 APIs for member record access (US Core 6.1.0, CARIN Blue Button 2.0.0, Da Vinci US Drug Formulary 2.0.1) and for provider directory (Da Vinci PDEX Plan Net 1.2.0), plus payer-to-payer PDEX exchange. Centene publishes twenty APIs through a partner portal at partners.centene.com, whose catalogue and OpenAPI documents are served anonymously; the FHIR Provider Directory is callable in production with no credential at all. Member data uses SMART on FHIR 2.0.0 standalone launch against a Ping Identity authorization server branded EntryKey ID; partner surfaces use OAuth client credentials with a per-API audience. Beyond the mandated interoperability estate Centene also publishes X12 / CAQH CORE EDI transaction, provider-search, product-mapping and care-management APIs.

Centene publishes 12 APIs on the APIs.io network, including FHIR Patient Access API, FHIR Provider Directory API, Provider RTR - FHIR PDEX Directory API, and 9 more. Tagged areas include Healthcare, Insurance, Managed Care, FHIR, and HL7.

The Centene catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Centene’s developer surface includes authentication, sandbox, documentation, API reference, getting-started guide, signup flow, support, and 30 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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/centene: open an issue to ask a question, or submit a pull request to add artifacts.
